Verilog Examples - Clock Divide by 4.5 It is possible to generate a clock divided by 4.5 or for that matter any number like N+1/2. It involves some math. In this example we will use a ring counter that counts on the positive edge of clock. ...

a parity counter is included in the JR module to detect the number of consecutive access to a request address.Fig. 6depicts the control flow for the read access to the data memory banks. The parity counter will output a signal, repeat_data_even, to indicate that Req_addr_S1 has been co...

The new verilog is a sequential circuit with only one multiplier, and a stage counter and multiplexers to control the data input to the multiplier: module builtin_counter_1(rst, clk, out); input [0:0] clk; input [0:0] rst; output [0:0] out; reg [0:0] stage_num; always @(pos...
Problem - Write verilog code that has a clock and a reset as input. It has an output that can be called out_clk. The out_clk is also a clock that has a frequency one forth the frequency of the input clock. It has synchronous reset and if there if the reset is 1, the output ...
