Width Spacing Pattern Support in Virtuoso Tools

Once you have created tracks in the layout using WSPs, you can do the following:

• Snap wires to tracks, as described in Width Spacing Pattern Support in Wire Editing.
• Snap objects to tracks during layout editing, as described in Width Spacing Patterns Support in Layout Editing.
• Check shapes in the layout for WSP conformance using the Batch Checker, as described in WSP Active Checking, or using the wspCheckActive SKILL function.
  You can use the environment variable, WSP_ACTIVECHECK_WIRETYPESALLOWED_ON_NOWIRETYPETRACK, to allow the shapes on the specified wire type, wireTypeName, to be created on WSP tracks with no wire type. This ensures that no violations are reported in WSP checker. Use the following command:
  setenv WSP_ACTIVECHECK_WIRETYPESALLOWED_ON_NOWIRETYPETRACK "wireTypeName"
• Use the Annotation Browser to view and manage the WSP Active check violation markers that are created by the Batch Checker or running the wspCheckActive SKILL function, as described in Finding Violations.
• Translate your design to Stream format, as described Design Translation Using XStream Translator. If you use WSP regions, your layer mapping file must have a WSPRegionType qualifier set, as described in Layer Mapping Support for Region Shapes.
