hello i've got one problem with .measure directive. i do simple dc analysis as .dc vin 0 vdd 0.01 and probe xtmp parameter ..probe xtmp=par('2*I(M1)/gmo(M1)') when i use .measure dc i(m1) at=0.2 it measures M1's drain current for Vin=0.2V. I want to have it for xtmp=0.2V How should i write the directive? regards
