Question

Verilog coding a D flip flop with D latches and an inverter

Use the verilog programming structure to create a D flip-flop module and test bench (named dff from a cascade of two D latches and an inverter . The
first of these D latches is typically called the master while the other is called the slave.
The truth table for the D flip flop, when the enable pin is high, is

where the up arrow indicates the rising edge of a clock pulse. If the enable pin is held low, nothing should change on the output of the D flip-flop. The D flip-flop module should follow the format

module dff(d, clk, enable, q, q_bar); input d, clk, enable; output reg q, q_bar;

{ ... put code here ... }

endmodule

I'm having some real trouble understanding this

Explanation / Answer

module dff(d, clk, enable, q, q_bar);

input d, clk, enable;

output reg q, q_bar;
