Update Constraint File script Version 1.0
|
|
|
|
In brief, you have the ability to change the swap group Ids for the pins of a
|
|
FPGA component on the PCB document without invoking the FPGA Pin Swap Manager.
|
|
These swap group ids are stored as records in the constraint file
|
|
part of a configuration in the FPGA project.
|
|
|
|
The sequence is as follows;
|
|
1) select pads
|
|
2) run script (which i would hook to a shortcut key)
|
|
3) pops a dialog where you type in a swap group number
|
|
4) updates/inserts SWAPID type records in this specified constraint file
|
|
|
|
if there are multiple configurations for this project...
|
|
you have the ability to choose which constraint file that targets the FPGA device.
|
|
|
|
Major limitation at the moment - for multiple records with same TargetIDs
|
|
the first SWAPIDs found for same TargetIDs are replaced only.
|
|
|
|
|
|
A warning dialog is invoked and scirpt is closed if the following conditions are met:
|
|
No PCB document
|
|
No selected pads on the pcb
|
|
No configurations
|
|
No Constraint files
