we all know that the parametric analysis is quite a useful tool in cadence, we can sweep any parameters in the design. I refer to the
cadence user guide and I find that it is a "for loop" simulation. I perform the same simulation by using the same "for loop" , but I find the parametric analysis is much faster than the common "for loop". I would like to know why the parametric analysis is faster? is there some optimization for the parametric analysis ?
I did a similar example. My simulation was a bit slower, but what I saw was:
The difference in speed between OCEAN and ADE is primarily all the printing it does to the CIW (or rather the code that has to pass that on). There are various switches to cut down the verbosity of spectre on the screen, but you can't turn it off completely. I think this ought to be possible (it could call spectre with =log instead of +log).
I'd suggest logging a Case with customer support.
