Good designs review presentation and good seminar series

Iron

hello all from Edmonton, Alberta

Iron

Warren,

 

Thank you for another great lecture.

Mike

Iron

Thank you Warren very good lecture!

All- online, webinars, websites, video.

New tool, documents.

fusion of old technology with new one or vise versa.

Thanks Warren it was a great class.

Iron

@All- Thanx for attending the class!

Iron

@Flux- Yes the SmartFusion2 devices can 'Zeroize' all the data stored in the device if it detects tampering. A nice feature!

Iron

Thank you very much, have a nice weekend!

Iron

?? a thought on security.   Can a program be written such that if we think the device is bieng tampered with, or its lost,   the program can instruct the FPGA to blow the code.

So an ASIC is one time programable whereas FPGA we can reprogram lots of times. I suppose we can reprogram it within the device via JTAG or usb.

ASIC is hard coded.

FPGA is all things to all people -- changeable.

Iron

@All- any other questions?

Iron

@Flux- An ASIC is 'programmed' by the manufacturer using metal traces. An FPGA is programmed by the user on their desk by using memory technology.

Iron

??? what is the difference between FPGA and ASIC?  

 

@rshankle, I might add that you could ask the vendor if they have  a migration path for that device

Gold

@rshankle- The difficulty with designs for an old device is not only part availability but ongoing support. It seem the old devices end up needed you to use the old tools which can be a problem if something doesn't work.

Iron

@All- Did I miss any questions?

Iron

?? Would you develop a new product around the Spartan 6 Xilinx chip?  (I'm not sure how much longer Xilinx will continue to make those chips or dev boards.)

 

Iron

@WarrenM Thanks, I'll check it out.

Gold

I like online webinars or online videos to present new technology. For detailed informaton for instance learning to program a device or a new language a video and printed manual are helpful.

Iron

@CG- You could use either Zynq or Arria for design #4. It just seems to me Altera has a slight edge there so I selected them as a target. Either would work however.

Iron

@chiarth - Thanks. Made a note of it.

Iron

Thanks Charles and DigiKey for the series.

Iron

@gordonmx, 78RPM- Several mid range MCUs now have some excellent DSP functions and offer pre-designed FFT functions. Check out Renesas and TI for example.

Iron

Thanks Warren, excellent week.

Iron

Thank you, Warren, for your responses.

Gold

@Bob Loy - take a look at Cypress semiconductors' PSoC

Iron

@78RPM- Interesting application. As to appropriate radios I think bandwidth and distance are the key elements. I have found that Microchip has a good range of solutions. Check them out if you have a chance.

Iron

@gordonmx, To find the frequency component of a vibration, yo have to do a Fast Fourier Transform. You will need a good 32-bit arithmetic unit and maybe a built-in signal processor. an MCU will require a lot of programming on your part. Better to get a signal processor on your device (not sure what device that might be).

Gold

Thanks, Warren. Have a good weekend.

Design 5 is a good example.  A future class, or version of this class, digging deeper into determining when FPGA is a better solution would be nice: hardware cost, measuring performance bottlenecks, etc.  Some MCUs are now including programmable state machines and complex timer logic that could solve a problem instead of a whole FPGA.  Discussion on how to debug and test FPGA implementations would be nice, too.

Thanks again for the interesting sessions.

@78RPM- Good point on medical devices. There is a difference between life support (like a pacemaker) and diagnostics equipment (blood pressure measurement). You need to look at the vendors infrmation to determine which they are applicable for.

Iron

Bob Loy- I think even simple MCUs will have FPGA fabric on them eventually. It might be 10 years away however...

Iron

@gordonmx- Finding the frequency component of the vibration could possibly be done with an MCU. Vibration is hopefully low frequency and I think an MCU could do it fine. If not, an external FPGA or an SoC FPGA could be a good target.

Iron

?? I often see disclaimers on devices that say they are not suitable for medical devices. Are all the devices discussed acceptable for medical devices? How is suitability determined?

Gold

? Do you think maybe simpler MCUs like Arduino will someday come with onboard FPGA (are they already?), or is that just adding a Ferrari engine to a Volkswagon?

Iron

Thank you Warren and Chuck for the execlent presentation.

Iron

Thank you Warren, Charles, and Digi-Key

Gold

Thanks, great lecture.

Iron

Thanks Warren and Charles, it is a great presentation.

Iron

Thank you, looking forward to more detailed walkthroughs

Iron

Thank you for your time, great presentation

Iron

Thanks Warren, this was a great presentation.

Iron

Thanks Warren and Charles for great lectures series. 

Iron

Thank you.  Very informative.

Iron

Thank you Warren, excellent presentation!

Iron

Thanks all, Excellent presentation Warren

Iron

Thanks. Great classes! 

Looking forward to the next one!

Iron

VHDL and more FPGA designs.

Class on VHDL and Programming FPGA.

Iron

What if you want to find the frequency component of the vibration?

Iron

FPGA, VHDL programming

Iron

I would like to see Introduction to VHDL

Iron

I fthe example is video project is best in next lecture.

Iron

cloud computation and its impact to embedded engineering field

Iron

please make this seminar 1 hour long  . this is interesting

 

Iron

A step-by-step tutorial on how to get specific processors up and running would be useful.  I realize there are almost an infinite number of options, but maybe a couple examples from each of the top few manufacturers would be useful.  All the way from selecting the processor through to getting code running on the chip in an embedded application would be useful.

analog - SAR/sigdelta/etc

Iron

I would like to see a class on low-noise A/D circuit front-end design.

Iron

I would like you can give me a detial development step basic on Altera and Xilinx on by one.

Iron

I would like to develop devices that sense multiple data in a remote environment - wildlife tracking and biological functions, water flow in remote areas. What kinds of radios are needed?

Gold

RTOS planning and workflow for integration of threads and tasks with RTOS, FreeRTOS preferred

 

Iron

A good topic would be a detailed run through one of the FPGA programming tools.

Iron

What is the new direction of engineering discipline?

Iron

PCIe programming. Basically how to get data from the dev board to the PC via this interface.  (what speeds are attainable? How are interrupts handled?)

Iron

Webinars should be done by engineers  NOT marketing hacks.

Iron

Whitepaper and online video and webminars

Iron

I need to go back and hit previous classes!

Iron

Warren's question: What additional classes would you like to see in the future?

Blogger

I like on-line videos if a good example is provided.

Iron

I prefer EDN and other articles, also white papers are good. In the past week I watched a horible webinar (Infineon IGBJT ) and a superb 2 hour webinar on hi speed PCB design by freescale. So it depends...

Iron

For Design #4, is the Zynq lineup as suitable as Altera Arria target ? 

Iron

THeoretical Understanding is one thing but Implementing this technology is another

Both have their own use.

Iron

I like webinars for an introduction and overview to the technology and papers for more in depth information

The best is hands-on workshops

Online videos but high resolution to view screens used to demonstrate tools, like HD full screen You Tube

Iron

I like articles and videos, webinars less so.

Iron

1.Prefer guided workshop

2. Article I can print so I can add my own notes

3 video tuorials.

in that order

Webinars for now - the PPTs work well for summarizing info.

Iron

A first person account of the actual use of the product works best for me after standard product description sheet.

Iron

Manufacturer Webinars for the product introduction. then articles for more indepth.

Iron

I learn from both online webinars like this as well as YouTube demos and white papers. It all depends upon quality.

Gold

Papers and docs mostly but online vids and webinars too are useful ... about 60/40

Both are important, online video and documentation, in order to understand better.

Iron

Yes I do  and make thing easy.

Iron

Prefer white papers, sometimes a combination of papers and online webinars.

Iron

online webminars/videos

Iron

I like all.  Most of my learning is by reading.

Iron

Short video tht highlight features, then articles

Iron

all -  what's ever available

Iron

Any input I can find (which is typically online articles). 

Iron

mostly read articles and watch video

Iron

prefer articles and white papers

Iron

Prefer a guided workshop

Iron

workshops are great as you can ask questions as they arise

Iron

Tend to read articles.  Scheduling live webinars is difficult.

Iron

online video is preferred.

Iron

The biggest challenges in learning a new technology or device is their huge mass documentation.

Iron

Warren's question: Do you prefer to view online videos and webinars to get an overview of new technologies and devices or to read articles or white papers ?

Blogger

We're on Slide 14, 15, 16.

Blogger

Classes like these are excellent for getting started in new technologies. Especially when the slides have references and links.

Iron

Biggest challenge is getting documentation which has a complete and accurate description of the product. For example the SmartFusion2 board has a SFP connector which is not included in the product description. It can be optical or electrical SFP.

Iron

Eval board promotions are helpful

Iron

Development and Eval boards. example code and documentation are very useful as well.

Guided lab/workshop with reference designs

Iron

To learn a new technonogy all of the mentioned resources is necessary. It's a combination of seminars, eval boards and vendor's tools.

Iron

proper documentation, vendor's software, IDE kits

Iron

demos, video tutorials

 

Iron

Evaluation board and manufacture website usually.

Iron

webinars are great too

Iron

A guided workshop using the workflow on a typical useful app is the best for me

For example, DMA use or Motor Control, etc

Iron

sometimes vendors come and do a lunch and learn explaning their new wares.

Most useful resources: evaluation boards, classes like this, vendor sessions at shows like ARM Techcon, DesignWest, etc.

Device manuals, Eval and reference boards, conference classes, and definitely webinars (like this one).

Iron

Web based searches, mfg app notes, techonlogy forums.

Iron

Evaluation tools and examples or reference design/code

Iron

using googling for documentation & more information

Iron

webminars, online training

Iron

onine courses like the CEC courses are very benifical.

dev kits, eval boards, sample designs

Iron

youtube videos, online articles, web based online courses

Iron

Eveluation or development board with manufacturer provided code examples are very helpful to me in getting a new project up and running quickly.

Inexpensive development kits.  Webinars like this.  Hands on seminars.

Iron

I've had to learn from development kits and manufacturer's documentation.  

Iron

Best resource is usually the vendor's online tutorials and documentation. These classes help narrow down a vendor.

Gold

For me, right now, it's been webinars like this one.

Iron

Seeing what the new device can actually accomplish in the real world

 

Iron

finding appropriate hardware meeting the design

These classes are an excellent introduction.

Warren's question: What resources have you found most useful in learning about new technologies or devices?

Blogger

It seems like I am out of sync with the live post.  The audio is on slide 5.

Iron

Documentation,evaluation tools at reasonable price and most of all time.

Iron

Inadvertently discovering gotchas or obscure settings that may or may not be in the device datasheet.

Iron

absorbing the documentation and uderstanding the new devices behavior/functionality

Iron

The second constraint is cost.  A large licensing fee is cost prohibitive for smaller research projects.

Iron

oh, and learning the language and macros available

Gold

Getting manufacturer's example code up and running the first time.

The details.  Have you seen the size of recent reference manuals?

Iron

My biggest challenge is usually schedule.  Projects are usually short scheduled.  Any technology that requires a long spin-up time usually won't fit into the project schedule.

Iron

Finding whatever would make me the most money

Iron

Documentation and lack of tutorials made embedded linux quite a challenge.

 Usually finding a technical support person knowledgeable enough to help translate the documentation

Iron

Understanding the tools in a short period of time is challanging.

Iron

yep - biggest challenge is justifying the time at work to learn

Iron

Challenge - the bewildering tool chains.

Iron

simulation and verification

Iron

Time  and getting the tools to run

Iron

documentation and getting familiar with new device

Iron

Time.  Apart from that, finding good tutorials.

Iron

Biggest challenge is to learn the vendor's software tools. Not hard but learning curve takes time.

Gold

Warren's question: What are your biggest challenges in learning a new technology or device?
