The Lynx Design System’s modular                                For more information, visit
architecture enables it to be customized              
to a variety of end-user design
environments. For example, steps in
the production flow are partitioned at
key logical handoff points (synthesis,
design planning, place and route, etc.)
which make it easy for customers to
plug-in custom “sub-flows” as needed.
While Lynx’s Production Flow is tuned
to deliver superior quality of results with
the Synopsys Galaxy Implementation
Platform, it can readily incorporate
internal or other vendors’ tools into
the design flow by updating standard
and well understood TCL scripts
and makefiles.
