New ContributorQuartus 18.1 fitter crash
Sometimes (after minor changes) during project compilation fitter crashes with an error:
Error: Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/vpr_common/cluster_legality_p...
Hi Eugene,
Please let me know if you are able to resolve this using below suggestion.
Update:
I am able to pin down the IE is triggered during heuristic accounting of input pins to a cluster. This heuristic counting is used to generate packing that give more flexibility for router to resolve local congestions for outlier designs, so it should be generally safe to disable this. I have tried the INI to disable this algorithm and the design is able to compile successfully.
Here is the encrypted INI (copy and paste this ini in your qsf) for 21.1 std (encrypted INI support is only avaliable for 20.1std or newer) then recompile.
