Checking Routability Using Batch Checker

Routability checks let you identify the problems with your data before the router is run. By independently using routing check, you can check the width, spacing, and accessibility of pins, and other issues that may affect routing. Because it checks the data against foundry rules, user constraints, and Wire Assistant overrides, it is important to set up the routability check options in the Wire Assistant before running Routability Check.

Routability checks are designed primarily for the Chip Assembly routing mode. Therefore, if you set the routing mode to Chip Assembly in the Wire Assistant, the whole suite of routing checks is available. However, if you set the routing mode to ASIC or Device Style mode, only pin access checks are available.

1. To perform routability checks on a design, select the Routability option. The routability checks are displayed on the right panel of the form, as shown in the following figure.
   
   
2. In the Scope group box, select
   • Current Editable Cellview
     Checks the current cellview. This option is selected by default.
   • Selected Net
     Checks only the nets that you currently have selected.
   • Exclude Selected Nets
     Checks all the nets except those selected.

For the other routability checks, such as pin checks, missing prBoundary, cover obstructions, and filter options, see Routability Check.
