Data Path Groups in OFFSET

You can also add a clock register time group.

TIMEGRP BEF = FFS(Out*); TIMEGRP DATA_GROUP OFFSET = IN 10 BEFORE CLK BEF;

This restricts the constraint to registers B, E, and F.

TIMEGRP DATA_GRP = PADS(DATA*);

NET CLK PERIOD = 45nS;

TIMEGRP DATA_GRP OFFSET = IN 10 BEFORE CLK;

• Data Path Groups allow the user to define a specific set of input pads to which an OFFSET constraint applies. Consider the following example.

A

B

D

C

Data1

Data2

Data3

E

F
