I'm having difficulties in achieving convergence in PSS simulation (corner dependent). This appears to be happening due to a few high impedance/tri-state nodes in the design getting capacitively coupled. Is there any way I can either loosen the tolerance or ignore these nodes for the simulation.
Also, can you please elaborate or provide an equation on how reltol, Iteratio and steadyratio are related.
Thanks,
Aman
