Module 6: Viewing Topology using SigXp Flow
You can assign constraints using the SigXp flow also. The SigXp flow allows you to view
the topology of the signal flows. It also allows you to assign constraints like propagation
delay and relative propagation delay.
Note: The constraints assigned through the SigXp flow are through ECSets. ECSets
are automatically assigned to the targeted nets after the constraint definition.
1. Open the CM UI. Select the DAC_CLOCK net. Do an RMB-click and select
SigXplorer.

2. Select OrCAD PCB SI from the Product Choices dialog box.
