1.3 FSM and Simulation

• Simulation cycle consists of two phases
• Signal update phase
• Process execution phase

• Combinational processes:
• Signal update at any time
• Process execution with new values and signal updates until no process execution necessary anymore
• Clocked processes:
• Signal update of CLOCK SIGNAL
• Process execution with currently (old) values of inputs and
  following (combinational) process executions.
• What if clock and inputs change at the same time?
