Methodology Compliance

The methodology compliance checker lets you verify that your design matches the desired coloring flow. It flags discrepancies between the design data and the multiple patterning flow setup. For example, it flags shapes having coloring information whereas based on the MPT setup they should have been not colorable.

The methodology compliance checker checks for the following:

• Colored LPPs: Flags any shape that is colored even if it is not part of the colored LPPs.
• Hierarchical Color Locks: The hierarchical color locks are checked using the environment variables, enableHCLCreation, enableHCLCreationOnPcells, globalColorShiftingPolicy, and globalColorShiftingPolicyForPcells.

A short summary of the discrepancies is reported in the CIW. A report is also created with details about each error at the current hierarchy level and inside the hierarchy. A marker is also created for each current level error. You can also view the marker in the Annotation Browser.

You can use the environment variable complianceCheckerReport to specify the file name and location of the methodology compliance checker report. The environment variable, complianceCheckerLimit, is used to specify the maximum number of violations that are reported by the methodology compliance checker.
