We use Allegro by Cadence for our PWB design package. We supply Merix (PWB fabricator) with three files. Merix converts these files into a IPC-D-356 netlist. Our software simply uses Cadence's extract tool to create the three files Merix uses. ############################################################## IPC Designers Council Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE DESIGNERCOUNCIL <your full name> To unsubscribe: SIGNOFF DESIGNERCOUNCIL ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
