I hope that some of you give me a solution to fix my issue.
I simulate my XO (32MHz, pierce topology) in HB, using the application note:
My issue is that sometime,(with the same Test bench and same artiste stat and settings) the linear IC fail to find out the initial frequency.
The result is that the final frequency is right but the magnitude is wrong. I'd compare with transient simulation (much longer), and when the IC linear works, the magnitude is right.
the rror message is the following:
"INFO: Can't find linear initial value. Using twotier Newton"
I'm using cds6:
I've the same trouble for jitter simulation with PSS. And my jitter is pretty bad because the SNR is low.
How can I do to remove the issue everytime ? because I don't know the reason.
Thanks in advance for your help.
