Hi, I use PSS and HB to simulate a LCVCO ( initial condition applied from convergence aid): from result--direct plot form: 1st harmonic is 2.36G: However, 2nd harmonic have the highest amplitude: may I...
View ArticleForum Post: RE: PSS and HB find wrong frequency as first harmonic
Perhaps you have a divide by 2 somewhere in your circuit? The oscillator output itself may be at 4.73GHz, but the analysis needs to set the fundamental to be half that if it needs to represent the...

Hi Andrew, tnx for reply, well, you are right. there is a divide by 2 after buffer.

Thanks for checking. It's odd, I just started a completely new testbench with a few levels of hierarchy and it seems to work perfectly. But I have a bunch of testbenches where it still does not work...

Ok, so the interacting setting is Spectre APS. I start with the testbench that saves all currents properly all the way down the hierarchy, but then I enable APS and the instance currents are no longer...

You're right again. I had all the proper permissions, but my session was in some weird state where it selectively didn't give me access to things I should have. I did 'newgrp this_group' on the...

I suspect this is an optimisation performed because using subcktprobelvl is expensive - you can end up with a lot of iprobes in the circuit which can significantly impact performance (particularly with...
