Following your word, got OP("/I0/I0/TP0", "gm") in display window, but how to display the result? I click "print", "printvs", "plot" ..., all don't display result of "gm", how to get it?
No idea - it works fine for me.. Check some options, look what's written in msfb (or icfb) window.
The other way how you can look at all transistor DC parameters is choosing Results->Print->DC operating points an dthen click on the transistor you are interested
Operation point can be obtained not only with DC analysis. OP can be saved during transient analysis in specified time points. Time points are specified in "infotimes" entry which is located in transient analysis options.
I am agree that it's more usefull to see all information about OP that only one value of Gm.
