13.3 XST - Verific Parser save net attribute prevents SRL inference even if value is "false"

Description

The 13.3 XST Verific Parser still prevents SRL inference even if the Save net attribute is set to "false".

This happens when -use_new_parser is set to "yes" while targeting a Virtex-5 device.The old XST parser is able to infer SRLs when the save net attribute is set to "false".

Solution

This is a known issue in the new parser.

To work around this problem, comment out the save net attribute declarations within the HDL code.
