Declare module and ports … Web2.1 Synchronous reset flip-flops with non reset follower flip-flops Each Verilog procedural block or VHDL process should model only one type of flip-flop. In other words, a designer should not mix resetable flip-flops with follower flip-flops (flops with no resets)[12]. Follower flip-flops are flip-flops that are simple data shift registers. great clips martinsburg west virginia
