How to measure the period of a RC oscillator exactly ?

measure statements .fsdb nanosim

hi,all
i am doing the simulation of a RC oscillator, in Nanosim . i want to know how i can measure the period of the clock output exactly in the turboWave . i have tried the TurboWave user manual ,but didn't get the answer .
thanks for your help !

If you are using hsim/nanosim, there is measurement statement. It's necessary to get more than 1000 period data and do statistic analysis to get mean period.

cscpoe can measure period
use it to open .fsdb file

thanks , but i want to measure the values of every period to get the variation of the oscillator output . any advice ?

thanks a lot first, if i use hspice to do the simulation, csope can measure the every period's value . but my question is how to measure it in Nanosim . can you give some information about .fsdb file ?

evercad can do the job. you can refer the user manual. the only thing you need to do is to write a measure script and run it with the .fsdb file.

but i don't have the "evercad" . any possible to share the software ?
