5 Synthesis

Libero passes the block timing to your synthesis tool when the top-level is synthesized. This timing shell enables the synthesis tool to produce more accurate timing numbers for top-level synthesis.

The timing shell also instructs the synthesis tool to treat the design block as a black box; this is done automatically—no action is required.

Use the synthesis tool options (Design Flow > Synthesize > Configure Options) for Resolving Place and Route Conflicts of blocks.
