padstack saved in .dra or .psm

archive

Hi,

I'm working with Allegro 16.0 (CIS and Layout). For an actual project I got a device as schematic library and the footprint as .dra and .psm file. When I generate the netlist for the layout, a warning is reported, that a padstack used in the symbol is not found.

I don't have the corresponding padstacks. I tried the following: Opening the the .dra file... The missing padstacks are correctly presented in that file. I used "Modify Design Padstack" to save them as file and tried a second time to export the netlist. Now the missing padstacks were found but a flash symbol is missing... I haven't found a solution to get the flash symbol out of the padstack.

Is my course of action completely wrong? I don't understand why the netlist creation needs the padstacks, when they are already in the files.

Regards

    Hi dear friend
    I found your name and post in Cadence forum and I faced the same problem which you hd with flash symbol and padstacks
    however I can not export any thing from .dra file
    I tried it more that 3 times and when I see the .log file for report it is indicating that no file is exported
    I tend to know how you solved this problem?
    were you working with Cyclone III devices footprint?
    I wanted to create the flash symbol too but I do not have the information of measurements and all that
    I appreciate your response
    regards
