I did without using SWAP file and APS is enabled.
By the way, I am getting following notice:-
Notice from spectre during IC analysis, during periodic steady state analysis `pss'.
Bad pivoting is found during DC analysis. Option dc_pivot_check=yes is recommended for possible improvement of convergence.
This is certainly not due to APS.
But I want to know why it is happening and where I can find "Option dc_pivot_check=yes" to make it "yes". What will be its effect.
I have attached the spectre.out file.
Could you please have a look at it tell me why the notice is cropping up.
