Hi Baolin,
Thanks for your quick reply! Don't worry about the crash, the work-around does the trick nicely. The netlist that I'm using contains a lot of stuff which I'm not allowed to pass on. Another similar example will probably show the same behaviour. Hopefully somebody from Cadence is reading this as well (Andrew? ;). But thanks for your offer!
Yes, MIC seems very useful. I've read somewhere that it can get the noise floor to levels of about -200dB! Great for oscillator design.
So am I right that FDTD, as implemented in Spectre, is a refinement method? So that always a (coarse) periodic steady-state has to be calculated first with Shooting-Newton (the combination Harmonic Balance & FDTD is probably a bit silly, right?). So MIC is as exact as FDTD (otherwise, why would you want to use MIC)?
I still don't really get when to use which method (FDTD/MIC). Could you give me some general advise?
I don't want to bother you too much with it though. Do you know of any good article on FDTD as implemented in Spectre?
Thanks again,
Paul
