Well, yes, Martin, but I willing to take on a complex development framework during the Corona virus downtimes for the benefit it might give me, as I get ready to produce another piece of unique technology this year.
I admit: so far without an EE formal education, but rather a CS background with practical hardware projects, I was 0.25 EE degree in 1989, 0.5 EE in 1997 when I developed broadband microwave equipment, 0.75 EE by the post-grad development from fundamentals to flight hardware. I wasn’t exposed to FPGA or DSP as I wasn’t in the EE discipline at all but I can do all the math.
No, I don’t want to spend time in getting to work. I estimate if I had been educated in class in using the toolchain like what I saw in the video I linked, and the tutorial that I am reading through, it would have saved me a whole summer’s worth of heads down work that I completed in 2013 on my own to take the lab bench parts (see picture) using MCF5270 to the proto-flight board (which had different pin outs and different peripherals and different BSP for the RTOS) that used MCF54415 family. To get around the requirement the flight software be mature, I had to develop my own ‘abstraction’ of the pin names/signal names/register maps so that I could (with limited money) test between the lab version (MCF5270) and the flight prototype EM-1 (MCF54415) interchangeably with a runtime firmware flag based upon what hardware was present.
Roughly this last year, I was coding BPSK modulators in C++ on my own just as a challenge, but I felt constrained by just programming and wanted to have real hardware to output a signal. Then I stumbled upon FPGA routines for generating carrier waves (ref: https://zipcpu.com/dsp/2017/07/11/simplest-sinewave-generator.html and http://www.andraka.com/files/crdcsrvy.pdf and it just hit me on the head: I was thinking 50 year old design methods: code first and then separately design the mod/demod using discrete blocks etc. etc. --

You are making extra work for yourself going Intel or Xilinx. Those design tools support a large variety of FPGAs - some of which are very large and complex and cost what a house goes for. You project requires a small, simple FPGA. Do you want to spend your time leaning a proprietary tool chain or the FPGA basics?

Wow, I am learning a lot thanks to Taco’s forums. I regret not paying attention to FPGA world earlier. I just sat through 30 minutes of a free training course on Intel’s website: and a wholesome review of a tutorial using the flow chart shown below – and it would I am most sure at this point, be easy for me to replicate my manually designed electric rocket subsystem (see pics from 2015) control system, into an FPGA version down to the 10 uS synthetic reprogrammable timebase I had to design, to validate my multi-rocket synchronization routines – I honestly was just paying attention to the physics, and not to the EE techniques then.
Back then I was using Netburner hardware, and wholly customized PCB, with IGBT power switches and ~40 amp transient discharges from an inductive energy storage system I calculated manually. Well --- an FPGA containing a soft-core MCU, some external switches, RTOS application (the same possibly that I used in the RTOS of Netburner environment) and some barebones serial comms seem to be practical to implement with these methods, …. And I may be able to develop new control processes and drive other elements .. without much delay ! Perhaps even use the onboard NIOS II DSP section to do mod/demod ? BTW, I liked the training material 100 and 200 level FPGA courses on the intel website, free with registration.

Here are a couple of books that might be of interest regarding Verilog:
This book is interesting, and a little bit different. It doesn’t require actual hardware for most of it’s content. I bought the Kindle version.
https://www.amazon.com/Designing-Video-Game-Hardware-Verilog-ebook/dp/B07LD48CTV/ref=sr_1_5?keywords=verilog+book <https://www.amazon.com/Designing-Video-Game-Hardware-Verilog-ebook/dp/B07LD48CTV/ref=sr_1_5?keywords=verilog+book&qid=1584203304&sr=8-5> &qid=1584203304&sr=8-5
THe title is accurate: a Concise guide to be sure. Again, not tied to any hardware, and somewhat light on details. Fairly thin.
https://www.amazon.com/Verilog-Example-Concise-Introduction-Design/dp/0983497303/ref=sr_1_1?keywords=verilog+book <https://www.amazon.com/Verilog-Example-Concise-Introduction-Design/dp/0983497303/ref=sr_1_1?keywords=verilog+book&qid=1584203528&sr=8-1> &qid=1584203528&sr=8-1
I have the Kindle version of this book. It uses a few specific boards.
https://www.amazon.com/Programming-FPGAs-Getting-Started-Verilog-ebook/dp/B01M0F1L5G/ref=sr_1_2?keywords=verilog+book <https://www.amazon.com/Programming-FPGAs-Getting-Started-Verilog-ebook/dp/B01M0F1L5G/ref=sr_1_2?keywords=verilog+book&qid=1584203803&sr=8-2> &qid=1584203803&sr=8-2
THis is more expensive, I have the paper version. It has the most of my bookmarks of any book I have. That says it all.
https://www.amazon.com/Embedded-Design-Using-Programmable-Arrays/dp/1589094867/ref=sr_1_1?keywords=Embedded+design+using+Programmable <https://www.amazon.com/Embedded-Design-Using-Programmable-Arrays/dp/1589094867/ref=sr_1_1?keywords=Embedded+design+using+Programmable&qid=1584204048&sr=8-1> &qid=1584204048&sr=8-1
There are several other books that I have. Like many other technical references, there is not ONE single book that is best.
I have used the Papilio and Digilent FPGA boards (among others) to help me learn most of what I have now forgotten, regarding FPGAs. I now have some newer boards boards based on Zynq FPGAs, such as the Red Pitaya, a MicroZed, and others. These are MUCH more powerful, but also much more complicated. My brain hurts whenever I delve into them.

Hi Martin, thanks for the tip. I went looking for the board you recommended from Lattice (it’s offered at a good price) but if I am not mistaken, it doesn’t have any peripherals such as switches for onboard experiments? The photos show it comes with LEDs, but no switches.
Then I went looking for the icestorm documentation and it seems they ship from UK (the blackice boards) so despite those development boards being chock full of accessories for experimentation, the shipping delay and cost sort of makes it expensive.
So, randomly I searched and came across (comments requested) for about $43.85 total with shipping:
https://www.ebay.com/itm/STEP-MAX10-Intel-Altera-FPGA-development-board/143318504573?hash=item215e72d47d%3Ag%3AlcQAAOSwARpdGDCw <https://www.ebay.com/itm/STEP-MAX10-Intel-Altera-FPGA-development-board/143318504573?hash=item215e72d47d%3Ag%3AlcQAAOSwARpdGDCw&LH_BO=1> &LH_BO=1
and according to the website http://www.stepfpga.org/step-max10-development-board/ it is fully supported by:
Altera MAX10 FPGA: 10M02/10M08
On board USB Blaster programming circuit
2-character 7-segment display
Two RGB LEDs
Four switches
Four push buttons
Eight user LEDs
Power from MicroUSB connector
40 pins DIP connector with 36 User I/Os

The software suite is … Altera (Microsoft) Quartus Prime Lite, which includes ModelSim for soft logic analyzer waveform output … and supports Verilog and VHDL. I think that could be ok for mid-level developers, right?
But since the documentation says “On board JTAG programming circuit”, is an actual JTAG gadget still necessary for this device, or is that functionality already included somehow?

You might want to take a look at https://www.amazon.com/LATTICE-SEMICONDUCTOR-ICE40HX1K-STICK-EVN-Evaluation-iCE40HX1K/dp/B00R3QU9K0 for a board and do a google search for Windows iceStorm support. The are more expensive FPGAs from Intel/Altera amd Xilinx but the tool chains are awful.
You also might want to check to see if you really want to invest in VHDL or if Verilog might be better for your needs. It doesn't hurt to know both but Verilog is more like C and is less trouble to learn.
Learning to simulate is a really import skill for FPGA development so you can get started with that before you have hardware.

I would like to do an experiment with an FPGA development board. I’m looking for something with pinouts or with a switch + LED; My experience with VHDL is very limited. I will be using Windows 10 for my development environment.
If anyone has a board they don’t need, would you be willing to sell it at a Tippy’s Taco’s meetup to me? Send me the product manufacturer part number and your ask to samudra.haque at gmail.com <mailto:samudra.haque at gmail.com> .
Also, if I had no FPGA board, is there a emulator environment that I can compile the code and get a testbench / diagram of the signals? At least I could begin coding / developing the framework right away.
