New Features Added to 5.8b
* A new subcommand for find has been added. find instances will find
instances in the current region which match the search pattern.
The usage is:
find instances [-r] <pattern>
* vsim -restore is now allowed in GUI mode.
* The vlog switch -instantiateReadOnly allows Verilog modules
compiled with -fast to instantiate modules or UDPs from library
directories which have read-only permission. The instantiations
will not be inlined or further optimized.
* The vsim option +delayed_timing_checks causes timing checks to be
performed on the delayed versions of input ports. This is used
when there are negative timing check limits.
* VHDL configurations now support loading Verilog configurations and
vice versa.
