Title: How to calculate the freq of the signal with vams?
Post by icsoul on Jun 10^th, 2008, 4:30am

Is there one command for this function directly?

If not, how to implement this function simply?

Thanks.

Frequency is the inverse of the period.
A period is defined as the delay between two positive crossings of a signal through a specified threshold (usually in the middle of the sine-wave).
So - what's the question ?

btw. maybe you should check the sourcecode section of designersguide :)

Thank you, Stefan

I'm newbie to veriloga. I do calculate the period, but an error is always be reported :(. Maybe the description method is not ritht.

Hint hint! There's a model for "Period measurement" -- click "Verilog-AMS in the upper right of these pages.
