4.4.3 Checking an IRS Net Assignment to a Routing Region
MSVT checks whether all IRS nets of a design are assigned to a routing region. MSVT lists all instances of IRS nets that are not assigned to a routing region in the Following IRS nets are not constrained by any routing region section of the report. If all of the IRS nets are assigned to an IRS routing region, the MSVT report omits this section.
Note: This is an informational section meant to identify nets that are not assigned to IRS region and does not cause MSVT to fail.
