Error trying to process blockram

guanix commented 9 years ago

I'm trying to create a very simple example of using blockram on an iCE40. My code is in this gist. yosys runs fine, but arachne-pnr gives this output:

You can also see that the .txt file generated appears truncated.

Forgive me if it's a problem with the Verilog file. I know that this isn't fully correct use of the blockram, but I wanted to isolate the problem. If there's a working example of blockram use out there, I would love to see it.

I'm at arachne-pnr d820f31fc3 and yosys eb38722e98.

Thanks for the detailed bug report. Fixed! https://github.com/cseed/arachne-pnr/commit/7052728dd03b8959616e3e3206cdc85f048c158f

Hi, I used a blif file to input Arachne-pnr for place and route. I got outputs that are .asc and txt format. Can I get .blif file from Arachne after Place and route, Just like VPR? Is there any possibility to get a blif file from arachne-pnr after place and route. Thanks

You can use --post-place-blif to get a post-placement BLIF (as you would have seen if you used -h). Post-routing BLIFs are not supported.

In the future please open a new GitHub issue, or use an alternative support method such as one of the IRC channels (##openfpga or #yosys), rather than posting comments on random old and unrelated issues.

Yes, That I used and got a post placed blif file. Sure, Thanks
