thank you.
 

Re: How to use .measure to test a signal frequency in Hspice

Can you be specific...

What signal freq? the output of your circuit ...and what is your circuit?
 

Re: How to use .measure to test a signal frequency in Hspice

I don't use HSPICE, but I can tell you how to do that in Eldo (not very different).

Extract the time at which your signal crosses in one direction a given threshold level for the nth time. Call that T_up_n.

Then, extract the time at which your signal crosses in one direction a given threshold level for the n+1th time. Call that T_up_n+1.

Hence, compute "1/(T_up_n+1 - T_up_n)".

Got it?
