I am trying to do a pre-sim of Sigma Delta ADC using HSPICE in 0.18um technology.
What I encountered is the simulation keeps stopping at a particular time for the same setup.
I know I should check the results of before the event of error, which I will do for sure. But what I am curious is, if it is a normal problem encountered with multi threading feature in HSPICE simulation.
The error I encountered is also shown in the attached picture:
8.2% time = 13.448015 ms ( etc = 1:04:22, ett = 1:10:09 )
( wall = 5:46 cpu = 1:26:15 s=14.9401 )
Tran switching to single inner/outer iteration (LDD) mode at time=0.013505 1.2e-12 , wait rebuilding
Error: Convergence Failure ... exiting at time point 0.0135051
