Slide 19 of 65
Notes:
The first process above executes once at the beginning of the VHDL simulation and then suspends until the input A is assigned a value of ‘1’ before it executes again. This cycle continues in that the process executes every time A is assigned a value of ‘1’.
The second process also executes once at the beginning of the VHDL simulation, but it then waits for 100ns of simulation time and executes again. This cycle continues with the process executing every 100ns of simulation time.
