| tryingCrypto | Does someone knows if there is a list of error codes for abc? I am getting error code 139. | 21:20 |
|---|---|---|
| daveshah | tryingCrypto: do you get any more log output than that? | 21:23 |
| tryingCrypto | I have the full log | 21:24 |
| tryingCrypto | For yosys, not abc. Is there an way to output more? | 21:24 |
| daveshah | No, usually abc does output something when it goes wrong | 21:25 |
| daveshah | If you just run "yosys-abc" on its own, does the abc prompt start OK? | 21:25 |
| tryingCrypto | Yes | 21:26 |
| daveshah | So, the abc install is probably alright then | 21:27 |
| daveshah | What context are you using abc in? One of the synth commands? | 21:27 |
| tryingCrypto | No, I am doing the yosys-abc directly. I do yosys abc -dff -liberty gscl45nm.lib -D 1000 -constr gscl45nm.constr | 21:29 |
| tryingCrypto | I do perform dfflibmap before hand. I can share the script. | 21:30 |
| tryingCrypto | https://pastebin.com/7TS05ksQ | 21:31 |
| tpb | Title: # read all source files source "source.tcl" # # Load the ASIC cells into Yosy - Pastebin.com (at pastebin.com) | 21:31 |
| daveshah | At a guess, it could well be a bug in abc's liberty or constraint parser, they've had issues in the past | 21:32 |
| daveshah | You could try abc -nocleanup to save the files Yosys passes abc, then run yosys-abc on the script it saves in a debugger | 21:33 |
| tryingCrypto | The same yosys script that I sent, I also use for a smaller part of my circuit and it works fine. The biggest difference is that this circuit I am testing has registers. | 21:34 |
| tryingCrypto | I will try -nocleanup | 21:34 |
| tryingCrypto | Okay, so apparently during stime -p a Segmentation fault happens | 21:57 |
| daveshah | Probably an abc bug best reported upstream | 22:07 |
| tryingCrypto | I fixed the "problem". I wrote the abc script in the yosys manual, and gave to abc, instead of letting yosys run. | 22:49 |
| tryingCrypto | Apparently when run yosys directly it adds the command "retime", after dretime, which is not in the manual. When I did this, it now works. | 22:50 |
| tryingCrypto | Thanks for the help | 22:57 |
