Intermittent failures on 'telescopic_ota_with_bias' #901

Closed stevenmburns closed 2 years ago

stevenmburns commented 2 years ago

@srini229 @854768750 @Lastdayends This circuit is sometimes causing failures (every third for me) on the 'merge' level CI. I suspect that it is triggering a memory error. You can run it standalone as (assuming $ALIGN_WORK_DIR is set to $ALIGN_ROOT/work):

mkdir -p work/telescopic_ota_with_bias
schematic2layout.py ../../examples/telescopic_ota_with_bias/ -p ../../pdks/FinFET14nm_Mock_PDK/

or through pytest as:

CI_LEVEL=merge pytest -vv -k telescopic_ota_with_bias --max-errors 20 -- tests/integration

Here is my valgrind run:

PYTHONMALLOC=malloc valgrind --tool=memcheck -- schematic2layout.py ../../examples/telescopic_ota_with_bias/ -p ../../pdks/FinFET14nm_Mock_PDK/

with (partial---it is still running) output:

srini229 commented 2 years ago

@stevenmburns The invalid reads are from the symphony solver. I saved the ILP problem solved during placement into a LP file and solved the problem using the standalone version of "SYMPHONY" solver attached to valgrind. I still get the Invalid read of size 1. This is not causing any memory leaks though. We can maybe pass this as a test to the SYMPHONY developers.

stevenmburns commented 2 years ago

It is probably not the issue then. There is a bigger problem with the second error in the global router. Perhaps @854768750 or @Lastdayends can take a look. From above:

@stevenmburns

As suggested in the log, there is a physical information for the pin DB of subblock X_SCM_NMOS_M0_M1 is empty.

I have looked in the lef file. The DB pin is empty. Maybe @arvuce22 should have a look on this.

@stevenmburns @Lastdayends There were some issues in the netlists. We have fixed all the netlists (i.e., examples) in #895. Now all these issues should get resolved.

arvuce22 commented 2 years ago

@stevenmburns @Lastdayends Now I am not facing any issues in "telescopic_ota_with_bias". Please let me know if it does not work at your end.

@parijatm @soneryaldiz @kkunal1408 @arvuce22 This problem has disappeared but a new one has emerged on the same block. It is still failing the master merge check. When run in standalone mode, it sometimes passes and sometimes produces this error:

@kkunal1408 @arvuce22 In looking at this more carefully, it seems that we are getting different parameter values of the devices in different runs of generate_primitive_lef: This is a failure:
