Reviewing PRCs

Overview of Quilter’s PRC reports, detailing how to interpret results grouped by constraint types, view passing and failing checks, and understand individual physics rule evaluations.

Overview

Every layout job comes with a PRC report that summarizes the results of physics unit tests Quilter runs for each of the defined layouts in your job.

The goal of PRCs is to help assess whether the layout candidate generated by Quilter is likely to perform as expected.

PRC reports show the results of checks for each physics constraints defined for your layout job

Interpreting PRC results

How PRCs are organized

Quilter's PRC reports are generated for every candidate Quilter considers.

The PRC results are organized by the parent constraint type they support – for example, bypass capacitors, differential pairs, and so on. You can expand or collapse the individual results for each constraint group by clicking the header for that constraint type.

A summary of the aggregated PRC results is also available on the right side of the constraint group header. You can filter the PRC checks shown to view all of them (the default) or only the ones that failed to pass.

Reading individual results

Along with grouping by constraint type, PRC results are also organized by the physics constraint they support. You can see information about the associated constraint on the left side.

PRCs that pass are shown in green, while those that fail are displayed in red.

Each PRC includes:

• The name of the check that was run

• The check's result

• The tolerances that indicate a passing result for that check

A complete list of PRCs, including the physics justification and assessment methodology, can be found in Physics Rule Checks (PRCs).
