To start, we instantiate a clock-divider module so that the clock signal that drives our counters (and other glue logic) is 1 or 2 Hz (slow enough that we. Accumulator reg ACC // Accumulator // logic to create 2 phase clocking when starting nand u0(m1,start,m2) īuf # 10 u2(Phi0,m1) // First phase clocking not # 2 u5(m4,Phi0) Īnd # 2 u4(Phi1,m3,m4) // Second phase clocking assign Finish = (State = 9) ? 1'b1 : 1'b0 // Finish Flag // FSM always posedge Phi0 or posedge Phi1 or posedge reset)Įnd else if((Phi0 = 1'b1) || (Phi1 = 1'b1)) begin // 2 phase clocking if(State = 0)īegin ACC <= 5'b00000 // begin cycle ACC <= A // Load AĮnd else if(State = 1 || State = 3 || State = 5 || State = 7) A combinational mux be achieved using dwikles answer, but if you really want to end up with flops (in that case out should be of type reg or logic, which is missing in your original code), then you can write: always (edge clk) begin unique case (clk) 1b0: out < in1 1b1: out < in2. You must place it's instances in your rtl. As others mentioned, using clock as data is not common. 7 4x1 Mux 4-Dig 7-Segment Display BIN to BIN to BIN to. The best way is to use PLLs or MMCM (Xilinx) if possible. Write a Verilog module for the circuit of the digital clock shown in Figure below and implement it. Wire Phi0,Phi1 // 2 phase clocking wire m1,m2,m3,m4 The core idea of a clock divider implementation is the same as with using VHDL. FPGA projects, Verilog projects, VHDL projects // multiplier 4x4 using Shift/Add Algorithm and 2-phase clocking system // Verilog project: Verilog code for multiplier module mult_4x4(
