Hello,
I have a problem with routing the differential pair out of the constraint region (under a big BGA package). Single ended tracks change the width on the border of the constraint region and this works fine. The problem is with the differential pairs as they don't resize directly on the constraint region border but they resize in random place (the point where I click the mouse) later.
Here I have some screens:
1) This presents that single-ended track resizing works OK. On the constraint region border the track resizes correctly.
2) Here is the actual problem. When I am in the routing mode (F3) and when I move the diff-pair out of the constraint region it doesn't resize automatically.
and then I click the left mouse button outside of the constraint region and the diff-pair is resized directly in that point:
The license I am using is "Allegro PCB Designer (was Performance L)". The Allegro version is 16.6 S050 (v16-6-112DX).
Do I have to configure anything else to get it working?
Best regards and thank you in advance for your help,
Krzysztof
