Need help with .meas translation from LTspice

QSPICE
1

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?

I reduced the schematic to as few components as possible.
It looks like “td” delays the find command from the first occurring flank and not from time=0.
