Gil, We have a tool called SiAuditor that allows us to do multi-board extraction directly to Hspice. It performs pre-layout and post-layout waveform and timing analysis with both Hspice and IBIS models. Once pre-layout is set up, the post layout becomes a highly automated process. Take a look at our website www.sisoft.com to learn more about SiSoft and our capabilities. Please contact me offline if you have any questions.

Using the results, we have concluded about the traces length, width, topology and so. We used this data to constrain the layout (we are using ALLEGRO). For the most part, we used HSPICE for the SI simulations. Now we are at the point that the layout is about to be ended, and we seek a method to perform a post-layout simulations. 1. Does anyone now of a way to combine the HSPICE and the ALLEGRO? 2. Does anyone have any recommendations at all for what to do or not to do? I appreciate your time and knowledge.
