Allegro Constraint Compiler: Workshop Learn more at Cadence Support Portal - https://support.cadence.com © 2019 Cadence Design Systems, Inc. All rights reserved w orldw ide. Page 14 Object Table The Object table creates various constraint objects, their members, and Type classifications for reference in other tables. The Rule Set and existing Constraint Set references could be made during object group creation as well a Count check to ensure that all the expected members are selected in the design. The Nets or Signal column entries are limited to XNet/Net objects which can be selected in the design using explicit net names or with a partial net name and a number range specified within curly brackets "{n-n}". For more complex net name selection, Regular Expressions are also supported and if the net name contains a square bracket, a forward slash ("\") could be used so it is treated like a regular character. If you select all XNet/Net members for group assignment, which are already members of a different type of group (Net Class, Net Groups, Diff Pairs), the existing group will be added to the newly created group. For example: If you select all members of a Net Group to create a Net Class, the Net Group object will be added to the Net Class. If you select both members of a Diff Pair for addition to a Net Class, the Diff Pair object will be added to the Net Class. All objects created by the compiler will be labeled with an "A" in the Sub-Filter field, indicating an "Auto-generated" object, with compiler options to mark "Auto-generated" objects as Read-Only.
