SDC contstraints ignored when using LE as storage with DCFIFO IP core

Description

When you use the DCFIFO IP core and select LE as the storage implementation, the autogenerated Synopsys Design Constraint (SDC) template is not valid. SDC constraints are ignored and the design is not constrained properly.

This affects the DCFIFO IP core when you select LE as the storage implementation.

Resolution

Modify the generated SDC template with the corresponding graycounter and synchronizer naming.
