Chris,Test results myhdl 15 sec yosys 11 sec The resulting files are located at https://github.com/develone/raspberrypi2_yocto.git The folder benchmark_yosys contains the file bench_mark_yosys.txt the steps I used and the files generated on RaspBerry Pi 2B. It also has the iceiver folder. Note chmod +x iceriver/icestick.sh to make it work. Now need to compare the generated files that you got on Ubuntu.Let me if that is what you wanted. I do not have a board to test the bin file.Regards Edward Vidal Jr. e-mail [email protected] 915-595-1613 On Monday, September 14, 2015 10:28 PM, Christopher Felton <[email protected]> wrote: On 9/14/15 2:32 PM, Edward Vidal wrote: > Hi Chris, I added code to compute the shasum and now the make test is > running longer.

I don't have an R2 (or 1) to test but the following is an example starting with a myhdl file, generating a bitstream for an icestick using the open-source tools [1]. I built this into some automation stuff I have used in the past. Running the example on my old'sh ubuntu system I get: >> time python ex_icestick.py real 0m3.6s The above converts the simple myhdl file, then runs the yosys/arachne/icestorm to generate the bitstream. I don't have an icestick so I couldn't test it.
