AR# 4839

説明

Urgency: Standard

General Description:

When constraining a design with OFFSET IN/AFTER and/or

OUT/BEFORE, with no PERIOD constraint, the period is

assumed to be 0 ns. But there is no warning or error

message during implementation. The only message that will

appear is the following when there is not Period constraint or

the Offset is to tight.

There is no minimum offset greater than zero for this constraint.

ソリューション

Create a Period constraint for the design.
