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 Sad

. Maybe the description method is not ritht.
