Meng Yu Bao, You can use the models from Mentor's ICX tool and let ICX take care of the trace modeling and writing the circuit file. It is very easy to use this way. Contact your local Mentor Graphics Application Engineer (AE) for assistance. If you don't have the contact information for your local AE contact me directly and I can help you find the contact.

Hi all Had someone done the simulation the signal integrity of the vertex II of xilinx fpga with Hspice, I have downloaded the Hspice model of the vertex II, but the model puzzle me. I do not know how to design the netlist of Hspice with the the model, I just want to use the vertex II model downloaded and rlgc circuit from my PCB for SI simulation, could someone give me some guid,thanks all ! ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
