Problem parsing blif file #75

Open lfigiel opened 6 years ago

lfigiel commented 6 years ago

I am getting an error from arachne-pnr:

arachne-pnr -d 1k -P vq100 -p src/iceblink40.pcf bin/top.blif -o bin/top.txt bin/top.blif:1443: fatal error: unknown model `$_DFFSRPPP'

blif file was generated with: yosys -q -p "synth_ice40 -blif bin/top.blif" src/top.v

I am using the following versions: arachne-pnr -v arachne-pnr 0.1+203+0 (git sha1 7e135ed, g++ 7.1.1 -march=x86-64 -mtune=generic -O2 -fstack-protector-strong -O2)

yosys -V Yosys 0.7+207 (git sha1 ea805af6, gcc 7.1.1 -march=x86-64 -mtune=generic -O2 -fstack-protector-strong -fPIC -Os)

Any idea ? Thx

I'm having the same issue. The project was building and working fine (in Atom IDE), I make an edit and 'boom'

arachne-pnr -d 8k -P cm81 -p pins.pcf -o hardware.asc -q hardware.blif hardware.blif:3244: fatal error: unknown model `$_DFFSRPPP'
