I’m successfully running these measurement commands in LTspice but they don’t work for me in QSPICE. Syntax looks correct to me except for possibly “time”. But there is a trace named “Time” available so I would have expected that to be ok.
.meas tf1_p FIND time WHEN V(Vo)=1 TD=149m FALL=1
.meas tr1_p FIND time WHEN -I(L2)=(ILs/2) TD=tf1_p RISE=1
Is there something wrong with the .meas? And if so, can someone give me hint on how to approach this in QSPICE?
