Build Problems and OS X Support

[srtemp]

I'm trying to get this toolchain (minus vivado) running on Mac OS 10.14.6, and have run into a few problems; some may be Mac related, and perhaps that's unsupported, but some seem more general.

Following the Readme: Set up all tools and added them to my path, set appropriate environment variables. $ source settings.sh no such file. From the git history, it looks like it's been renamed env.sh, so I used that instead. $ make env no such target. Looks like make conda might be appropriate, since we're setting up a python environment. So I ran that, and did some manual setup that I don't recall at the moment to get things running. $ python3 fpgaperf.py --toolchain arachne --project oneblink --device "hx8k" --package "ct256" --board "breakout" fpgaperf.py: error: --family argument required. Looks like it's missing a required flag. Looking at the next example, I set family to xc7. This may well be wrong, but it made the tool run. That ran the Yosys portion successfully, but then generated the following error: End of script. Logfile hash: af0a50ac80, CPU: user 0.38s system 0.06s Yosys 0.9+1706 (git sha1 2bda51ac, gcc 10.0.1 -fPIC -Os) Time spent: 44% 12x read_verilog (0 sec), 14% 1x share (0 sec), ... arachne-pnr -d 8k -P ct256 -q -p empty.pcf oneblink.blif -o oneblink_arachne.asc oneblink.blif:10: fatal error: unknown directive '.subckt' make: *** [oneblink_arachne.asc] Error 1 rm oneblink.blif

This looks like something I've run into before when trying to read hierarchical blifs with tools that don't support them. But at this point I decided to ask for help. It seems like the readme is out of date; if anyone could direct me on how to properly get started with this tool, I'd really appreciate it.

Thanks, Scott

Thanks for filing this @srtemp.

Regarding the various README issues you are right, there have been quite some changes lately and the README is out of date, I will update it accordingly.

Currently, ice40 tests are not being run in CI, therefore it may be that the blif error is a latent bug in fpga-tool-perf. I'll try to add that as well to the benchmarks run in CI.

@srtemp FYI, the README has been updated

Thanks @acomodi I'll give it another try! I appreciate you working on this so promptly

@srtemp If you don't mind using Nix on your Mac, you could try: https://github.com/HackerFoo/nix-symbiflow

Then, in your checked out repo, run:

nix-shell /path/to/nix-symbiflow -A fpga-tool-perf --use-prebuilt-symbiflow false

It will take a while.

@HackerFoo Thank you; I'll give that a try. I just moved to using a VM with 16.04 and have gotten it running, but a native install would be much better. I appreciate it.
