ADE could not see the voltage signals

Tony,

Can you show the bottom part of the input.scs (all the options, analyses, and save statements etc - everything to the end of the file - no need for the circuit part)?

My guess is that you're not saving the voltages, but seeing the netlist would confirm that theory.

Regards,

Andrew.

Hey, Andrew, the bottom part of the input.csc :'simulatorOptions options reltol=1e-3 vabstol=1e-6 iabstol=1e-12 temp=27 \

You have save=none which means that it will not save any voltages. You want save=selected so that it saves the "selected" nets (i.e. Vgs, net16 and net14).

Yes, I would like to save it. Regards, Tony Zhang

That's fairly obvious - I just was telling you that you need to set save to "selected". If it's set to "none", the voltages you've requested won't get saved. This is on the Outputs->Save All form in ADE.

Andrew.
