CHAPTER VIII FINITE STATE MACHINES (FSM)

• Synchronous sequential system • Behaviour depends on the inputs and outputs at discrete instants of time. • Flip-flops, registers, and latches that are enabled/controlled with a signal derived from clock form a synchronous sequential system. • Asynchronous sequential system • Behaviour depends on inputs at any instant of time.

• async_cmp.v - (see Example 3 in section 5.3) - this is an asynchronous pointer-comparison module that is used to generate signals that control assertion of the asynchronous “full” and “empty” status bits. This module only contains combinational comparison logic. No sequential logic is included in this module.

4. Asynchronous Control signals: There should not be any internally generated asynchronous control signals 5. Do not mix the positive and negative edge triggered flip-flops 6. Avoid use of latches in the design 7. If shift registers are used then do not replace them by using scan enabled flip-flops but only ensure the enable control 8.

A sequential system can be defined in terms of its inputs and present state. That is, the next state of the sequential system ... Such circuit is also called asynchronous since the only pulse required for the operation is the clock pulse. The JK Flip Flop have the J and K inputs both tied high, which allows them
