<tryingCrypto> Does someone knows if there is a list of error codes for abc? I am getting error code 139.
<daveshah> tryingCrypto: do you get any more log output than that?
<tryingCrypto> I have the full log
<tryingCrypto> For yosys, not abc. Is there an way to output more?
<daveshah> No, usually abc does output something when it goes wrong
<daveshah> If you just run "yosys-abc" on its own, does the abc prompt start OK?
<tryingCrypto> Yes
<daveshah> So, the abc install is probably alright then
<daveshah> What context are you using abc in? One of the synth commands?
<tryingCrypto> No, I am doing the yosys-abc directly. I do yosys abc -dff -liberty gscl45nm.lib -D 1000 -constr gscl45nm.constr
<tryingCrypto> I do perform dfflibmap before hand. I can share the script.
<tpb> Title: # read all source files source "source.tcl" # # Load the ASIC cells into Yosy - Pastebin.com (at pastebin.com)
<daveshah> At a guess, it could well be a bug in abc's liberty or constraint parser, they've had issues in the past
<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
<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.
<tryingCrypto> I will try -nocleanup
<tryingCrypto> Okay, so apparently during stime -p a Segmentation fault happens
<daveshah> Probably an abc bug best reported upstream
<tryingCrypto> I fixed the "problem". I wrote the abc script in the yosys manual, and gave to abc, instead of letting yosys run.
<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.
<tryingCrypto> Thanks for the help
