Hi,
I have a simulation in ADE assembler where I run a transient sim first and use the final condition of the transient sim (Writefinal -->spectre.fc) as an initial condition to pss sim (readic).
In my tran sim I have a low pass filter that I need to disable for ~300ns (using a pwl source to control) and enable after, to make sure that the filter output voltage is settled to correct value. When I run PSS sim, the tstab sims will see the PWL source in the schematic and start the tstab sim after final transition of the pwl source. So if I set the tstab time to 200ns, the total pss sim will be 300ns+200ns = 500ns.
Is there a way to change the variable that control the filter on/off between tran/pss sim? I tried using the dynamic parameter and set the filter pwl source to transition at 1ns in pss sim, but that doesn't seem to have an effect. The pss sim logs show that its reading my parameter new value but the tstab sim still runs for 500ns.
Here is how I am setting the filter control signal in pss sim:
Is there another way to do this?
I can also make a run plan in Assembler and have a separate sim for tran and pss, but then I have to write the full path of the spectre.fc for pss "readic" which get cumbersome over multiple corners.
Thanks a lot,
Hamed
