Would like you to give a training on Introduction to FPGA

Iron

Have done it, few designs with FPGA: Altera, Xilinx

I've never programmed an FPGA. Sounds like an art.

Iron

I have not done any programmable logic designs....yet

 

Iron

really new ... still catching up,

Iron

Max -- on every slide you should write out the synomym PLA, PROM, etc.  I'm having trouble keeping score on all the names. 

Iron

pargraff,

good morning,

I have attempted and failed at Mirco chip.

Iron

This is all new to me. Thanks for the info.

Iron

Thank you for the classes

Iron

Programmable logic CPLDs (MACH devices) & FPGAs (Xilinx)

Trying to catchup due to conflict.

 

Thanks Max

Another facinating lecture

No I havent done any of these types of devices

Thanks Max. Wonderful Lecture. Can someone let me know what are GALs on slide 8 and PLL on slide 25

Iron

Great presentation Max! Thanks.

Xilinx & Lattice devices.

Catching up early today.

hmm I am late I think

 

Iron

Max, I noticed when I try a link (and lose this page) and then try to come back to it, it starts SLOWLY rebuilding the conversation. But if I right-click and "reload" or "refresh" at that point, it almost instantly jets straight to the top of the list of posts. Maybe it will work for others... (i'm using Chrome)

seeya tomorrow.

Iron

I was just being funny.... I don't even use an oscilloscope, but I stumbled into that video and thought it might be a good resource to share. I do sympathize with people trying to learn new subjects, Sometimes it seems like there is too much info on the internet, a lot of it very specialized, and it can be difficult just trying to find a GENERAL INTRO on something that covers the bases without going too deep. That is one reason I appreciate DigiKey and Max for doing a series like this.

Iron

And thanks to Kentj and danlafleur for answering my early question regarding how you learned about these sessions.

Iron

Thanks all for the lively conversation!

Iron

pcbJack - I'm the opposite; much rather read than watch (usually, anyway) - why take 5 minutes to watch something I can skim and read in 60 seconds?    (but then, I'm old, as my kids keep reminding me...)

So long, Max and all. As always, I will e-see yal tomorrow.

Iron

No problem, Max - we'll see you tomorrow!

@MAX: Browser problem? Not to worry. We already have emanated a lot of energy in the air by now! :o)

Iron

Errant - that doc pcbJack posted shows a bunch of equations to figure it out (page 4) but says rule-of-thumb is 5X the fastest clock in the system.   That jives with my memory (but I didn't post an answer 'cause I wasn't sure my memory was right...)

I'm sorry everyone -- it will take me ages to recover (like 30 minutes to reload all the messages to come up to date) -- I'll have to sign off now -- I hope to see you tomorrow for the final session...

Re "Cray on an FPGA" .. it's easy to forget how far we've come so fast -- the article I mentioned says "1983, the Cray X-MP was the world's fastest computer -- Dual CPUs, 16MB of RAM, and a peak performance of 400 Megaflops" ... not so impressive by today's standards...

 

Blogger

OSC. BANDWIDTH: It is simple. Decide how manu periods of the fastest clock on a digital circuit/system and/or the fastest harmonic component of an analog signal you want to reproduce and "measure" sith clarity on the osc. screen. That is the answer. Am I close, MAX?

Iron

is vhdl enough for fpga designing

 

Iron

Excellent Max.  Thanks.  I had trouble finding intro. stuff on oscopes at vendor sites.  I'll check that out.

Iron

yeah, I'm kiddin' ya... but seriously, I just fouind a LOT of info about that just with a general search on "oscilloscope bandwidth". The answer i saw more than once, specifically, is that your o-scope should be at least two times the highest frequency in the device. I'm sure there is more to it, just telling you what I saw

Iron

I asked Mike Dunn who is Editor in Chief of www.ScopeJunction.com -- he replied: In some ways bandwidth is the least important parameter.  For a 100 MHz clock rate, you need a bandwidth of at least 350 MHz.  More important are things like triggering, sampling rate (for digital scopes), pulse capture, etc.  It would take at least an hour to explain all of the factors involved.  Look here http://www.tek.com/learning/oscilloscope-tutorial for tutorials.

Blogger

The question from yesterday was:

"How does one know what oscilloscope bandwidth is required for a design? e.g. if MCU is 100MHz, what bandwidth of oscope is required? Is that the right question to ask?"

Blogger

Cray on an FPGA???   oh, that hurts my brain... 

OH -- may bad -- I forgot about that oscilloscope question from yesterday -- I did get an answer -- give me a moment...

Blogger

pcbJack:

 

Thanks ahole.

Iron

Re the mention of implementing a Cray on an FPGA -- you are right -- a Cray Supercomputer from I think the 1980s was recently replicated on a single (not so big) FPGA by a young designer -- check out thsi article: http://www.programmableplanet.com/author.asp?section_id=2340&doc_id=247408&

re: oscilloscope bandwidth, just discovered a cool resource called "Google"

Iron

@Luizcosta: Re your question about natural language -- I'm not sure -- if we get to the point where th ecomputers knwo wha twe are saying, then we are at the point where they can design themselves -- check out my review of Robopocalypse by Daniel H. Wilson http://bit.ly/SW6A6j

Blogger

oh, boy!   each URL makes me jump to another few pages, and those again...   It's gonna be a long night...    (a long *fun* night!   :)

FUN PROJECTS: I read some cool reports from folks who have implemented several CPUs such as Zilog Z80 and other processors using FPGA. Even a CRAY implementation can be found on the web.

Iron

Max:

RE Yesterday's Q on Oscilloscope bandwidth, did you get an answer from ScopeJunction as planned?

Iron

i learned vhdl in college and was very interested to work in that

Iron

I hope CEC will provide a 5 days FPGA lectures like this! Thanks!

Iron

@luizcosta - perhaps eventually, but not any time soon; natural languages are too ambiguous, and constantly evolving

Xilinx, Altera, and Digilent have very affordable started kits for students.

Iron

Re the logic Analyzer - -that's the Open Bench Logic Sniffer -- check out that Hamster article I just mentioned -- he talks about it there...

Blogger

Also "Hamster" in New Zealand just did a blog about the different FPGA boards he has -- check out thsi article: http://www.programmableplanet.com/author.asp?section_id=2340&doc_id=247935&

Blogger

@MAX: Don't you see a time when discrete digital logic thinking will no longer be necessary,  when all solution thoughts will be implemented by natural languages?

Iron

Thanks very much Max !

Is it possible to get the lecture audio archive as well, along with the Slide deck.

Iron

@Samdisp06: Re looking for an inexpensive FPGA dev kit. Duane on APP (AllProgrammablePlanet) is uasing an $89 one (search for "Discovering FPGAs") -- but Gadget Factory gave us a special offer on one known as a Papilio Board for about $35 -- check out this article: http://www.programmableplanet.com/author.asp?section_id=1925&doc_id=247412

Blogger

Max, Wher is the logic analyer you mention before?

Iron

...and that "nixie" watch probably doesn't include an alarm.

Iron

What common items have Zynq-7000's or other FPGA's in them?

Iron

@EdB_Vt: which Huntsville are you going to be in and when? And you have evidence that Max will also be in this same Huntsville sometime soon? Inquiring minds want to know....

Iron

Hi MAx,

 Thanks. I thought a couple of comments on combinational vs LUTs and why LUTs are used might be helpful.

Cheers!

Iron

@MAX: you did fine on the time because, you just needed to stress some important ties between ASIC and FPGA.

Iron

Max, Is processor speed and clock speed determined by the processors ability to dissapate heat?

Iron

@Vinaya: Again. I think you will find the discussions on AllProgrammablePlanet.com to be  agood place to start ... do a search on "Ask Max" and "Ask Adam VHDL" and "Discovering FPGAs" (that will keep you busy for a while :-)

Blogger

vinaya - me too!   Anyone in the Boston area interested in taking on an FPGA intern?  (years of programming experience; no FPGA experience)

@Max: no need to apologize. We were all here with you. Great lecture!

Iron

@richnass: thanks for letting Max use the full hour. Fantastic!

Iron

looking for inexpensive fpga development kit for learing!

Iron

i've been around electronics for 40 yrs and just started playing with Arduino. i'm like a kid in a candy shop!

@Vinaya: I think FPGAs are a REALLY good area to get into. Before you learn FPGAs you need to understand basic digital concepts -- then you are going to have to learn a hardware programming language like Verilog of VHDL (which is the best is aon on-going debate)

Blogger

Thank you a fourth time for a fourth very nice talk.

Iron

Are there any FPGAs that have DSP processing built in ?

Iron

Thanks Max, have a nice day all.

Iron

waiting for the next 

Iron

Max - please!  No apology necessary - great fun listening to you talk.   And I personally enjoy the rambling nature - makes it quite fun.

@Jay: "Can't wait for tomorrow's lecture."

Me too -- I wonder what I'm going to say (I'm amking this up as we go, you know :-)

Blogger

I knew a programmable logic talk would run long

Blogger

Hello Max,

I want start a career in fpga design. can you tell me where to start

it was a good lecture today thanks

Iron

we enjoy your enthusiasm for your subject

Iron

Time to earn my keep, thanks Max and Rich. See all tomorrow.

Iron

Rich - we need more weeks with Max!   (Max willing, of course...)

Good presentation thanks

Iron

GREAT FUN..  THANKS!!1

Thank you Max !

Is it possible to get the lecture audio archive along with the Slide deck.

Iron

Sorry I ran on so long -- I thought this would be a quick one -- it's a case of "wind me up and watch me go"

Blogger

When we are in Huntsville, we can "do lunch" with Max, fill in the gaps here, and drain a few pints.

Iron

Can't wait for tomorrow's lecture.  Thanks Max!

Iron

I wish we had more time!

 

Max, you have nothing to appologize for.  your course is extreamly helpful.  Thank you.

Iron

Thank you Max. I really learned a great deal! See you tomorrow.

Iron

Thanks Max, a great way to spend my lunch time. almost like dinner and a show.

Iron

Thank you Max, this was the best presentation of the week, so far. Very interesting series, even for us oldies.

Iron

Excellent presentation, thanks!

 

Max - thanks for another awesome session!   Gave me a good begining understanding of FPGAs   (and stirred up some desire to go play with them!   :)

Thanks Rich, Max, and everyone.

Iron

Max, where are you speaking from?

@Max: no need to apologize. We were all here with you. Great lecture!

Iron

thanks Max and all on chat

Iron

Thank you Max ,good presentation

Iron

Thanks again Max and Rich. Need more time next time..

Iron

Very informative session and I have added allprogrammableplanet.com to my favorite list.

2 Questions: 1. Is there a hobbyist/experimenter/workbench kit for "playing" with these devices and the associated logic much like the Arduino or is there a better way to learn this?  2. What common items have Zynq-7000's or similar FPGA's in them? Thanks for these classes.

Iron

sounds like programming in machine code

Iron

thank you Rich and DigiKey ... looking forward to tomorrows presentation

Iron

Thanks a lot, was a pleasure! And good night (here 10 PM).

Iron

Same time same station. Right?

Iron

thank you, good information

Iron

Thanks Max.  Was great info!

Iron

so if he had killed her would the T1000 have shut off?

 

Iron

Thanks for the session, Max.

Iron

@richnass: thanks for letting Max use the full hour. Fantastic!

Iron

wow lots of infromation, thanks

 

thanks again Max...great information and intro

Iron

sorry folks, that was beyond my control

Blogger

Thanks Max! Great class.

Iron

I also suspect that the Titantum used in fabricating these chips contributes to the heat dissapation.

Iron

Great Pres. Max. Had no problems with audio today, we made no changes on this end???

Rich - thanks for url

 

Thanks pcbjack.  That's what I thought.  I appreciate the straght forward terms you put it in.

www.allprogrammablehere's the URL Max mentioned: http://www.programmableplanet.com/

what is the website again, please?

 

www.allprogrammable____?

Iron

thanks for the pull up explanation ...reduced noise makes sense...(mechanical guy)

Iron

agree with pcbJack...

Iron

from V=IR to Dual ARM cortex in three days...

Iron

and of course there is always Max's books if you really need to learn more about this....!

Iron

PULL-UPs: Are generally used as "line drivers" on "open collector" device outputs. They are good to reduce noise on the transmission link.

Iron

@shorek - without pull-up, line will float unless it's being pulled up or down by a logic gate.   floating means you won't be able to predict what it is.    pull-up makes it predictable value. (usually a '1' - then logic gate pulls the signal down to '0')

Is that true with MCU with a internal GPU array

 

Iron

Thanks pcbJack for the link!  Too bad Max didn't anticipate acronyms as being a stumbling block to us

Iron

Yes, I think the point is that Max is combining early history so we can see how the technology grew, and now the devices are so complex that you can't assimilate it all in your mind. The goal is to have a general understanding of where we came from and how fast the technology grew, but to really design ASICs and FPGAs you will ned a LOT of VERY specialized training. This is just an intro...

 

Iron

@bmatts - changing a logic line from "0" to "1" requires a small bit of charge (electrons), changing from "1" to "0" requires that to be drained to ground. Mulitply this by a gazillion logic gates and gigaherz clock speeds results in significant current flow. High current flow results in heat generation.

Iron

yes I am serious.  Tx

Iron

@skorek A pull-up resistor is used to pull-up a floating input (or output) to a logic 1

Iron

@Shorek

pull-up resistors are used to fix a know logic

Iron

@pcbJack-Thanks for the link.

Iron

@skorek, a pullup resistor (or pull down) provides a default logic state when the input is inactive or not connected.

Iron

and current source really

Iron

pull-ups or pull-downs set the logic to a known state (1 or 0)

Iron

@shorek - are you being serious?

@skorek keeps logic High on an undriven signal

Iron

What is a pull-up resistor and why do we need to use it?

Iron

@luizcosta -

You're right from a literal sense, of course.  Otherwise the signal flow wouldn't allow for independent OR gates.  The way it's drawn is obviously just to simplify the diagram.

What is the relationship between processors and clock speed?  With clock speeds up in the GHz does the chip have greater heat dissapation?

Iron

Mux is a switch to choose LUT or input D

Iron

Serializer-deserializer

Iron

no IAALAU (i am as lost as you)

Iron

Maybe a comment on combinational vs LUT?

Iron

what's the difference between the editions of 'Bebop to the Boolean Boogie'?

Iron

@RudySchneider: I appreciate your comment. however, if you look closely to the boolean equations in all the examples, you'll realize that those vertical lines with the cross-connect on the vertical line, they imply a three wire connection to the output OR gates. By the way, SOP stands for Sum of Products like in the boolean equation w = a & B & C | A & B | A & C, which requires 3 input OR gates. 

Iron

@bmatts - Max is getting to a slide on current "re-programming" technologies. Just wait for it.

Iron

I HAVE USED DEVICES FROM PLDS TO MCUS IN EXPERIMENTS AND DESIGNED CIRCUITS TO MAKE UNITTS EXPANDABLE.

UVEPROMS were erased using UV light then came EEPROMS that were electrically erasable.

 

Iron

EEWms-- some of these were brand names, "PAL" was trademarked, so we ended up with a whole bunch of acronyms

Iron

@bmatts, yes, the UV discharged the floating gate in EPROM

Iron

@bmatts - old UV erasable PROMS

Iron

@EEWms - no, not the only one...but seems to be the nature of this technology/industry ;)

Iron

So what your saying is that the floating transistor are reset with untraviolet light?

Iron

am I the only guy stumbling over all these acronymns?

Iron

CPLDs are in circuit reprogrammable.

 

Iron

@pcbJack - except for the reference to GALs

Cleared by UV rays through a window, I think...

Iron

nothing he has described so far is "reprogramable"...

Iron

Max, Your reprogrammable logic.  What happens internally with the chips that you clear?  How is the reset achieved. 

Iron

used UV erasable eproms

Iron

@luizcosta - not necessarily.  THese are "wired-OR" gates.

in answer to the previous question: yes, designed with xilinx

Iron

@MAX: It appear to me that, for the beginner, the output OR gates on the PLA diagrams should indicate that they have 3 inputs (to implement the SOP sythesis teqhnique).

Iron

@fwjava - i agree

Iron

Shouldn't the middle connector line read   ' A & c ' ??

Iron

I used many eprom in the past

Yes, I have used and program PLD's PROM and EPROM's  from Signetics (Philips now NXP).

Iron

I have a few UV eraseable EPROMs lying around the office somewhere...

 

Iron

WOM!??? Write Only Memory? Honeywell had a a spec for that -- I remember it well!

Iron

Replaced an entire 8 x 11 circuit board by replacing logic with a prom back in the dark ages, tried to patent but three other guys beat me out.

Iron

@Rudy "I remember the WOM!"

Got one at home, along with the glasses & rubber nose that came with it!

Iron

'forgot to check in - from Queen Creek, AZ

I have used PROMs and EPROMS

Iron

Hello from Tucson

 

Iron

Used UV proms in my past

Iron

hello guys! I'm late and missed a lot of good info's :'(

Iron

I have used PROMs, EPROMS, and EEPROMS in past; nothing recent

In the early days used small proms to emulate logic circuits back in 70's.

Iron

no audio issues (so far)

Iron

I use a lot of 8-bit Microchip PIC's

Iron

My company uses FPGAs in some devices, but I don't have any personal experience with them.

Iron

No, I haven't used a programmable logic device before

Audio was lost for 3 seconds?

Iron

Used UV eraseable PALs from Altera

Iron

At least the location the audio player was supposed to go cleared this time.

Iron

@luizcosta: that's a good idea (to statr early), but the system we employ for this doesn't allow for it.

Blogger

I've used an STM8 microcontroller.

Iron

@rich - yes, I have (programmable devices in general), don't have personal experience with FPGAs but our company uses them extensively

Iron

Have not used fpga or plds

Iron

@RudySchneider - thank you!

Iron

caa028: Have you ever worked on a design with a programmable device? If so, which manufacturer did that part come from?

Blogger

@caa028:

Only general question was "have you ever used programmable logic devices (and/or FPGAs)?

(presuming Rich asked question about what we've done with programmable devices)   haven't used FPGAs; interested in learning about them.   have used some stuff long time ago

I'm 5 minutes late - did I miss any questions?

Iron

We use FPGAs at our company, but I don't design them.  Love to learn about it...

Iron

no FPGA design yet

Iron

Yes did a lot of designs with 150-200 7400 ICs. Long time ago..

Iron

I have 74 series logic part numbers burnt into my finger tips.
