Simulation environments
A simulation environment for a VHDL design (the Design Under Test or DUT) is another VHDL design that, at a minimum:
Declares signals corresponding to the input and output ports of the DUT.
Instantiates the DUT and connects its ports to the declared signals.
Instant...
This example deals with one of the most fundamental aspects of the VHDL language: the simulation semantics. It is intended for VHDL beginners and presents a simplified view where many details have been omitted (postponed processes, VHDL Procedural Interface, shared variables...) Readers interest...
