feature allow place-and-route,
and static timing analysis of designs prior to licensing
Secure register transfer level (RTL) simulation models allow
simulation with user design in third-party simulators
Performs synchronous optical network (SONET)/synchronous
digital hierarchy (SDH) framing and transport convergence (TC)
Processes transport overhead (TOH) and path overhead (POH)
Supports a data rate of up to 155.52 megabits per second (Mbps)
