You can create a Designer
Block with or without I/Os.
A Designer Block can be
synthesized, simulated, and placed-and-routed the same way as a regular design.
You can lock the place-and-route of the
Designer Block to ensure performance does not change.
Performance and
place-and-route can be fixed absolutely; however these rules can be relaxed
gradually, if necessary, to ensure that you can integrate the
Designer Block into your <top>
project.
You can use all the features in
Designer Blocks in SmartDesign.
