Dear all, I encountered two problems when using Hspice, and have no idea with the causes. 1、There is some warnings : resistance is negative, it may cause instability problem. I wonder what this warning means, how it comes, and how to clear it. 2、When doing transient analysis of PLL, a run-time error occurs,as showed in the attachment. I don't know where to locate the problem. So, would you please give some advices, thanks.
