DC after Tran

Pirate King over 2 years ago

I followed the instructions from the link 9 years ago but it does not work for me now;

How to simulate DC sweep after TRAN? - Custom IC Design - Cadence Technology Forums - Cadence Community

The tran is required for startup of the circuit.

I sequence the DC after tran and on DC options I set readns=spectre.fc and useprevic=ns or yes

I can see the DC log saying that the file is being read and if I open the file the values make sense but back annotation does not show correct startup voltage nodes

Quite hard to answer without seeing it (customer support would be better), but this might be due to having sources in your circuit that have a DC value that are not consistent with the final value of that source in the transient).
