current measure statement

wbsm over 5 years ago

What is wrong with the following statement;-

.meas tran ir0 find i(Ibot.Iarray.Il.I128.Il.I0_7.Itr.N0:s) at=6n

When i use this it keeps saying the following:-

WARNING (MDL-358): ......meas" 6: probe 'I( Ibot.Iarray.Il.I128.Il.I0_7.Itr.XN0.s:1 )' is invalid.

I am using Spectre (R) Circuit Simulator Version 19.1.0.237.isr3 64bit -- 3 Jan 2020

Thanks

Because .measure is a SPICE statement, you need to use the SPICE statement to do this. I'm assuming that the "s" pin is the source of a MOS transistor, and so the "s" pin would be the third pin. So I'd expect you to have to use:

.meas tran ir0 find i3(Ibot.Iarray.Il.I128.Il.I0_7.Itr.N0) at=6n

I've tested this with similar circuits - I() returns the current through the first terminal and I1, I2, I3 etc through the first, second, third etc.

Regards,

Andrew.
