Description

I am trying to complete the OpenLane flow for my sequence detector design... The design runs pretty well when I go about the ./flow.tcl -interactive method and runs perfectly well till routing but is failing when I try to run the complete flow using ./flow.tcl -design iiitb_sd. Here iiitb_sd is the name of my design file that contains netlist and other related files.

Expected behavior

Complete the flow successfully till step number 43 and have assertive feedback saying "Flow Complete"

@McLucifer2646 I confirm the attached test case crash STA run. OpenLane tag: 2022.08.25 is month back commit. Can you update OpenLane commit to latest and confirm the same issue repeat again?

vijayank88 commented 1 year ago

with latest OpenROAD commit (https://github.com/The-OpenROAD-Project/OpenROAD/commit/a783d1b9cf1e0feab152007b603e203a614c1519) it crash during report_power seems.

@maliberty please assign to right person.

jjcherry56 commented 1 year ago

The underlying problem is that the fast and slow liberty files are missing the sky130_fd_sc_hd__inv_2 cell. The libraries have to be exactly congruent for multi-corner analysis. I will work on adding checks for broken libraries, but in the mean time you should get the libraries fixed. There are no doubt other cells with the same problem.

maliberty commented 1 year ago

@RTimothyEdwards @donn please look at the library consistency issue (fyi @mithro)

McLucifer2646 commented 1 year ago

WELL, the problem got fixed, I changed the fast and slow liberty files as advised by @jjcherry56 and I got an affirmative green check saying "Flow Complete".

Thank you @maliberty @jjcherry56 for helping me out with my bug and special Thanks to @vijayank88 who taught me how to report an issue on GitHub leading to the solution.
