Clock divider vhdl2/2/2023 ![]() This code is not tested, but it looks ok to me. A clock divider takes an input frequency and the output frequency is equal to the input frequency divided by some integer. The outputs to the clock will be a binary number from 0000-1001 (0 to 9 decimal). You need to look at the initial conditions. 16 bit counter and 10 Hz clock divider By attaching a clock divider to the input clock, we can drive the 16 bit counter at 10 Hz (ten times per second). I got a result for my simulation about 0.499s rising clock and 0.98 falling clock. Then, I want to get a simulation result about 50 duty cycle of 1Hz clock. I used a VHDL code and Modelsim Tool for clock divider. Figure 3 shows FourBitFreqDiv.vhdl to use the. Ap_clk2 : assert property ( ( posedge clk ) # 1 |-> clk2 =!$past (clk2 ) ) Īp_clk4 : assert property ( ( posedge clk ) # 2 clk2 = 0 |->Ĭlk4 =!$past (clk4, 2 ) ) // The antecedent #1 and #2 are just used for initialization, since the clk2 and clk4 have not started. Hi everyone, I have a question about simulation (30MHz -> 1Hz clock divider). Figure 2 shows schematic design for four-bit frequency divider by using four T-type flip-flops. ![]()
