Giovanni, HSPICE simulation speed dependes upon the type of model your using. If you use IBIS models and Tlines, HSPICE simulation takes no longer than any other IBIS simulator. However, if you want (or need) to use transistor level models, S-parameters, etc, Then HSPICE runs take more time, but you get the accuracy and flexibility you need. SiSoft's SiAuditor solution allows extraction from Allegro, Board Station, PowerPCB, and Expedition PCB. The extracted simulation files contains lossy and lossless transmission line models.

You'll find all the lines in a RLC format (not wlines or other...) Isn't Hspice too slow for a complete postlayout analysis? By! (I'm interested to other reply too) Giovanni -----Original Message----- From: Sidney S [mailto:sidney16481@xxxxxxxxx] Sent: Wednesday, June 11, 2003 6:39 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Hspice simulator for board designs Hello, We are exploring the possibilities if using Hspice simulator for motherboard designs (for mailnly post layout). But Hspice does not have the option of directly importing the routed board file. Hence can anybody suggest any method for doing post layout simulation on a routed board file using Hspice? Looking forward for your reply!!! Thanks, Sidney --------------------------------- Do you Yahoo!?
