I have build a VB program that builds a schematic and board file based on some user inputs. I am seeing a problem during the board build section. I am using the command line interface to open a blank Allegro board file and run a script which runs a SKILL file that builds up a complete board. The problem I am seeing is that the build of the board is sometimes very slow. If I open Allegro seperatly, run the script with the File -> Script command the program runs much faster. I have looked online and there are mentions of memory issues with command lines.
Has anyone else seen this problem or does anyone know of a faster way to open a board file and build it up with a SKILL program.
You can turn off the master DRC switch and disable dynamic shapes (Display -> Status). When you are finished constructing the board, turn on dynamic shapes, update them and then do a drc update. If adding constraints to a board, it is much faster to load them via a techfile instead of using Allegro scripts to load individually via constraint manager (e.g. avoid "cmgr" commands in your script)
You should also look at your script and remove any "zoom" and "roam" commands. Leave any "trapsize" commands since they are required.
