I have heard (but not personally seen) that the flow for this is supposed to be IC tool > APD > Allegro. Do you have an APD license? -- George Patrick Tektronix, Inc.

I need to convert a file from the IC layout tool to a physical part in Allegro. I can attempt to import the streaming file but Allegro wants to make it .brd file. The positioning is extremely important because this is what is called a bump die which has no leads and connects directly to the IC's substrate. I know this can be done because I have a few examples but the original source is not available. Any help will be great. Regards, Ron Scott C.I.D.
