I designed a voltage amp which will work under a large temperature range. Can any one tell me how to plot the output resistance vs. temperature with hspice. Using .tf I can only get one Ro value at one simulation.

Thanks!
 

you can sweep temperature.
In awaves, change x-axis to temperature, and plot ro
 

Can you post specific command? Thanks!
 

can awaves plot ro?I don't know
 

same question : CAN awaves plot "ro" if yes wat is the options in hspice netlist for post processing.
 

Use .ac analysis and plus .net command. probe zout, that is what U want. good luck.
