Good tools presentation.

Iron

More of software designer.

 

Iron

Catching up... Q.1: more of software designer

Iron

Currently I am in the process of prototyping with a target design in mind.

I experienced simulation for smaller example projects on Spartan board.

-Raj Panchal

I missed the live session for class 3. I am systems person mostly SW but now getting into HW.

Hi,

    Because of time difference ( India ) I was unable to participate immediately.

    It was an excellennt presentation. I am a hardware engineer and may be I understand the logic behind the software. I cannot go into codes directly. I am looking for the design of Microcontroller for Motor Control applications in Automative applications. The temperature  within the enclosure of this system to be planned is 180 deg Celcius. The competitors use ST Micrpcontroller L9805. The requirement is very precise control of the motor speed with position feedback, appropriate acceleration and deceleration. Uses CAN bus Communication from Engine Unit.

      Mr Warren, I would appreciate if you can suggest a suitable microcontroller to work at high temperature, automative applications very reliably. Where can I get some reference designs.

       Thanks

Iron

Used kits for FPGA, MCU, communication interfaces - cool toys to get warm

Did Simulations : FPGA - VHDL, Hyperlynx - SI and PI

yes but also create own protoype as eval board

Iron

usually 2 or 3 prototypes runs

Iron

Thanks.  See you all tomorrow.

Iron

Thanks Warren and have a great day.

Iron

@All- Ok, looks like I got all the questions answered. If I missed any, just que them up tomorrow! CU then.

Iron

@all- any other questions? Did I miss any?

Iron

rshakle- On the prices for the tools, it is best to check out the vendors web sites (or at Digi-Key) since the prices do change. Look for special deals too- sometimes if you attend a training you can get a big discount!

Iron

Thank you for Today's lecture Warren, now I will proceed to listen to it! :)

Iron

better late than never

 

Iron

@prashant436- I will try and cover a simple design on Friday that might be a good target for a simple CPU and FPGA (like you describe).

Iron

Great, thanks a lot Warren. I hope you can give a little bit comparetion on Altera and Xilinx device. Thanks again.

Iron

@ginomai- Combined FPGA and MCU is best when the MCU on its own can't hit your performance/power needs. If an MVU on its own is enough, stick with an MCU.

Iron

I'm working on project "to implement cortex m0 and peripherals on SPARTAN 3E fpga kit" so on friday plz suggest something on design

@Seaguard- Seperate FPGAs and MCUs can be a good way to get started. Since ARM is so pervasive now if you use an ARM MCU you can eventually move it into an SoC FPGA!

Iron

Thanks Warren, a great way to spend my lunch time. See all tomorrow.

Iron

@sherlock- Since the SoC FPGAs use dedicated CPUs the timing is fixed. If you access an external (in fabric) peripheral a dedicated bus interface is used so timing isn't changed. Only latency will be different for the peripheral depending on place and route results...

Iron

@tpyn- I don;t kanow that off the top of my head, but check out the web page I reference and it should tell you.

Iron

One question, if it is possible that the SoC core (MCU) timing will be changed after some self-made IP were added and recompiled design? such as NIOSII core it is comes from normal logic cell not an integreted MCU core? I am just interesting in here actually I don't met this problem. If they will happen on high speed possible?

Iron

@DBarth- Vivado was a new design so initially there were some issues but they have gradually been addressed. That might be the source of the negative feedback. It can be a copmplex tool, so someone who just wants it simple might find id daunting...

Iron

?? Would you happen to know if the Microsemi SF2 SFP connector is optical or electrical?

Iron

@WarrenM.  Thanks, that's where I'm at now with separate FPGA & MCU eval boards.

Iron

@prashant- The vendors tools only support their devices. You can't design for a Xilinx part using Altera tools for example.

Iron

Thanks Warren and Charles.

Iron

@Bob- You need to select the package for the FPGA/ SoC FPGA and that determines the number of pins available. If you need fewer pins you can use a smaller package.

Iron

Thanks - I'd heard mixed reviews and was curious about your opinion.

does Xilinx tool also support all these?

DBarth- Xilinx Vivado seems to be a solid tool to me. I have used it just a little (evaluation mode) but it seems to be very powerful. Could be a good way to go if you need the high-end features.

Iron

@Seaguard- The $30 or so kits are for FPGA only boards (not SoC FPGAs) but you can get started with them to learn about FPGAs. You can use a soft MCU however (implemented in fabric) to test out the MCU tool flow too!

Iron

??Many of the designs I work with utilize a separate FPGA and MCU - and oftentimes the MCU alone meet my design needs.  Are the shared resources / speed the primary reason to utilize a combined MCU/FPGA?

Iron

?? Is there a price range for the basic toolset for Xilinx/Altera/Microsemi ?  (That is not locked to a particular dev board.)

Iron

Thanks Warren and Charles

Iron

Thanks, Warren! Appreciate this going over all of these (relatively new) hybrid devices & their platforms -- very useful.

Iron

Thanks Warren and Charles

 

Iron

??Do you have an opinion on Xilinx's Vivado?

Thanks Warren and Charles.

Iron

If you have a question for me please use a ? or two at the beginning so I can easily find it.

Iron

Thank you Warren, Chuck, and Digi-Key

Gold

Thanks alot Warren, see you tommorrow.

Iron

Thank you Warren another great lesson

Iron

? You mentioned pinouts earlier. Can you specify different chip size / # of pins for a given MCU/FPGA system ?

Iron

?$30 Eval Board?
?Is that for a combined FPGA/MCU?
?If so, any specific examples?
I've seen FPGA only or MCU only for around $30. Lowest combined that I've found is the Micro Semi A2F-EVAL-KIT-2 at $123.25 plus $79.75 for daughter card (not in stock). It seems to be cheaper at the eval level to start with separate MCU and FPGA boards.

Iron

Thank you Warren for another great lecture.

Iron

Thank you warren, excelent lecture.

Iron

I've had vary varying experiences with quality of eval or dev kit hardware+software combination, meaning, some vendors are much much better than others about supplying you with a complete bottom-to-top toolchain (while others deliver general hardware along with a barebones software toolchain -- like, a C compiler with...maybe libc if you're lucky, and then maybe nothing else).

So if anyone's listening, providing a fully-useful set of tools for working on real projects out of the box makes dev/ev kits go so, so much further.

Iron

Actel SmartFusion A2F-EVAL-KIT Evalution Kit

Iron

Mostly TI and Freescale

Iron

I am using a zedboard for my current project

http://zedboard.org/

I see there is a less expensive version on the way

http://microzed.org/

for $200

Iron

I've used evaluation and development boards on the MCU side to become familiar with the processor and start the software design while developing the custom hardware.

Iron

Yes, Altera FPGA, their CyclonIII develop kits $499.

Iron

Yes, very helpful starting out with DSPs.  Used our own previous boards now.

Yes have used kits especially when looking at a part that is new to me, saves a lot of time.

Iron

I have used dev boards for MCU's.

Iron

Yes Xilinx Spartan3 & Coolrunner, Various NXP LPC evaluation boards.

Iron

Trying to use ZED board with reference design

Iron

Never got around to Eval/Develop boards - next step!

Iron

Yes, I prefer to start with a development kit the first time I use a µC.  I can't remember which ones right now.

Iron

dev kits have worked quite well for my design projects. I can start modeling fairly quickly.

Iron

Used several dev boards for MCUs, Atmel and ARM. None for FPGA yet.

Iron

I've used freescale development kits in the past

Iron

Yes, have used development kits to start new designs.

Iron

used Altera 's board before in classroom setting

Iron

Yes use development kits 

Iron

Yes, mostly for processor chips.

Iron

Yes, Altera Eval and Proto boards

Iron

Altium's Nanoboard 3000  (Xilinx Spartan 3AN )

 

Iron

Warren's question: Have you used evaluation or development kits previously- if so, which ones?

Blogger

Prototype vital parts of the design.

Iron

hello I am very late today

 

Iron

(And then, as someone else mentioned, iterate from initial prototype-as-development model works very well.)

Iron

Yes spent some time for prototyping, mainly on kit boards, and simulators

Iron

Usually I spend all time in prototype on the Altera drvalop kits first and then customlize to to our application.

Iron

usually spend time on prototyping, refine and distill until its right. sometimes system fragments get attention on the breadboard.

Iron

I spend at least 40% of the design time on prototyping.

Iron

Simulation previously - not typically

Iron

I'd imagine it depends on the type of work you're engaged in...generally speaking, for me, prototyping things quickly such that you can show someone a working proof of concept in short order can be extremely valuable

Iron

I spend some times on prototypeing, but more on final design.

Iron

I prefer to prototype at least parts of the design.

Iron

I will spend time prototyping the design, especially when there is a lot of new technology or new complexity.

Iron

Prototype subsystems on an evaluation platform.

Iron

Yes, prototype most of the time.

Iron

Start w/ general circuit and change as needed

Iron

Typically use a prototype.

Iron

I'm a prototyper - Lather, rinse, repeat repeat repeat.

Iron

Use prototypes to evaluate various designs and choose best for the final solution.

 

Iron

I try a couple of prototypes before settling on a design

Gold

We spend quite a bit of time in prototypes.

Iron

Depends on how much time is available

 

Iron

Depends on the design - some have multiple prototypes, some just one.

Prototype in small pieces, and integrate into the whole design step by step.

Iron

Try for specific solution, final design

Iron

I go straight to doing a final design

Iron

very limited prototyping

Iron

Prototype complex parts of designs.

Iron

We spend a lot of time going through various prototypes.

Iron

Jump right to the target and start designing.

Iron

I'm more of a hardware designer

Iron

Warren's question: Do you spend a portion of your development cycle prototyping your design or do you go right to the final design?

Blogger

I'm writing a simulator for a processor architecture, I'm tool-challenged otherwise.

Iron

Did a little simulation in the past, but found it to be more trouble than it was worth in most of our applications (SHARC DSPs.  Easier, in my cases, to just write/debug the code directly.  Not sure that will be the case with FPGAs.

Have had some but not much resently

 

Iron

MicroCap simulation experience, but no VHDL simulation experience.

Iron

I have never done simulation.

Iron

Yes, but I am a novice with regard to FPGA simulation.

Iron

have used uC simulation and analog circuit simulation. slightly familiar with Altera's set of tools for design and simulation.

Iron

never used simulation, the designs were simple

Iron

Simulation with ModelSim on FPGA design.

Iron

Wouldn't consider not doing simulation!

Iron

Some simulation, more of circuit analysis. 

Iron

Some simulation of micros, noFPGA

Iron

Very little, but hoping to learn more.

Iron

No simulation experience.

Iron

LOTS of simulation experience....

Iron

FPGA and CPLD simulation

Iron

No simulation experience...

Iron

Warren's question: Have you done simulation previously- yes or no?

Blogger

Sometimes Hardware designer, then software, and again and again :)

So 50%/50%

Iron

Somewhere in between...software tends to be easier [for me] to utilize to rapidly prototype (or fully develop) when possible (particularly where well-designed high-level libraries are part of a given ecosystem).

Iron

More on software engineer about 70-30%

 

Iron

70% softeware & 30 hardware.

Iron

90% software design.

 

Iron

I'm 60/40 toward software

Gold

I have no problem dealing with hw but spend most of my time with sw

Iron

I'm 50/50 split between hardware and software.

Iron

50/50, Tying the two together is what I enjoy.

Iron

Hardware 80% Software 20%

Iron

30% hardware / 70% software

 

Iron

certainly more hardware designer with software experience.

Iron

more software focused 

Iron

System designer, mostly software but now with VHDL, the distinction is blurred.

Hardware designer but also write embedded code to run the hardware.

70%hardware 30%software

 

Iron

hardware and software designer

Iron

Embedded Software Engineer...

Iron

Warren's question: Would you say you are more a software designer or hardware designer?
