... Next, we write the Verilog description for T_FF (Example 6-7 ). Notice that instead of the not gate, a dataflow operator ~ negates the signal q, which is fed back. Example 6-7 Verilog Code for ... Negative Edge-Triggered D-flipflop with Clear Given the above diagrams, we write the corresponding Verilog, using dataflow statements in a top-down fashion. First we design the module co...
