Hi, Everyone,
I posted a question on Phase Locked Loop several weeks ago and thank
you very much for everyone's reply.
Here I have another question related to hspice simulation on the phase
locked loops -- I want to measure the lock time of the loop using
hspice for 1000 times with different loop parameters. I tried to use
derivative of the VCO input signal and I tried to use the phase
difference between the reference signal and the VCO output....
basically, what I am using is the .measure command and find and when
function.
However, all the things I tried do not work -- it does not really
predict the lock time for me.
I read the hspice manual and I cannot find an existing function that
can directly do it. Anybody here has some ideas, please?
Thanks a lot!
