saving in a previous version

carl carley

we are running version v17.2 and have modified a customers design which was in v16.6. as 17.2 is not backward compatible is it straight forward to export a placement & routing file from the 17.2 pcb to be imported into the 16.6 version?

Delete all the routing etc and use the 2 files and regenerate the pcb data in the 16.6 version

i know exactly how to do this in other pcb tools but i'm new to allegro!

regards

carl

    Files such as .brd, .mcm, .sip, .dra, and .pad, which are saved in version 17.2, cannot be opened or downrev’d to 16.x. The recommended practice is to maintain both 16.6 and 17.2 databases/libraries.

    If you try to downrev any of the above files from version 17.2 using File — Export — Downrev design, the tool will display the following message:

    Padstacks (.pad) and symbols (.psm, .bsm, .fsm, .ssm) created in 16.x will load into 17.2 databases.
