Description: The PVS constraints checker issues an error with a Layout XL license issue when working with the constraints editor in Layout EXL: "Virtuoso Layout XL License is not currently checked out. This license is required to enable the OBC CV flow. Reopen design using Virtuoso Layout Suite XL or GXL license."
This is because the new Layout EXL application is not fully supported for PVS-CV and OBC-CV flows.
Solution: There is currently no workaround for this issue.
CCR 1984334: Limited options in Pegasus drop-down menu when launched through Layout EXL
Description: The Pegasus menu has only limited options available when invoked in Layout EXL. This is because menu options are added based on window type and "VLS-GXL" is no longer a valid window type in IC23.1. Pegasus has not yet been updated to add "VLS-EXL" as a supported window type.
Solution: There is currently no workaround for this issue.
