Test fails when unit testing

Open jingyao-zhang opened this issue 3 years ago • 2 comments

Hi everyone. I have a problem when I am running unit test 21_ngspice_delay_test. The tech scn4m_subm can pass the test but freepdk45 cannot. According to the sram.log file, the error is ERROR: file delay.py: line 708: Timed out, could not find a feasible period. Is there any way I can get the relative accurate delay under freepdk45 ?

This is an issue that the PTM models from FreePDK45 aren't included by default. It can't find the models and so simulations fail with whatever default device models are in ngspice.

Thanks for your help! I have successfully passed that unit test under freepdk45.
