What kind of information?
What testpoint to use or how many point needed per net?
The information we need is the number of testpoint on a net.
we tried to add such "user defined constraints" in CEA already.
What we found as a show stopper here was the fact, that all user constraints are stored in the user settings.
So if a user has created this user constraint column "number of testpoints needed", the colum will not be visible for the other users.
You should check this out first, if adding constraints in CES by automation does fit to your working process.
I'm aware of the setting in the user interface, but I think we can overcome this problem, by changing the setting file to all user or by writing a script that adds this column when opening CES.
The thing that I'm more concerned about, is how to transfer this data to the Test point interface in the PCB environment.
We want to use the back annotation capabilities already implemented in the CES.
Right now, we have a way to transfer the data to the PCB, by using a script we wrote using PCB automation.
We prefer to use the capabilities that mentor supplies without writing extra automation code.
Also, by using CES as an interface, we will be able to see what is actually implemented in the PCB compare to what was asked from the user.
