8.12 Generating a Combinational Loop Report

The Combinational Loop Report shows all loops found during initialization and reports pins associated with the loop(s) and the location where a loop is broken.

To generate a Combinational Loop Report:

From the Tools menu, choose Reports > Combinational Loops.
The Combinational_Loops Report Options dialog box appears.
Select either Plain Text or Comma Separated Values.
Click OK.
