I will design the de-bouncing circuit in a later post. Multiply each digit by its binary value and add. may be other more efficient methods) would be to: decimal to binary. (as opposed to simulation) you need to do the conversion with a. every time the push button is pressed due to the bouncing problem related to push buttons the counter will be incremented many times for each time it is pressed. If you're trying to do decimal conversion to and from binary in hardware. This is not the best method, but if I use clock here without any debouncing mechanism the counter will not be accurate, i.e. In place of the usual clock I used the push button (always posedge button). The above program is so simple it needs no commenting, the thing to note here though is the always block. So every time the push button is pressed the counter will be incremented by 1, the LED's will present the binary counter.Īlways (posedge button or posedge reset) Note: this gray to binary conversion doesnt require the feedback of the bi i+1 to produce the bi bit (it only relies on the. module b2g ( parameter N 4 ) ( output N -1:0 g, input N -1:0 b ) assign g b ( b > 1) endmodule. Now that we have the blinking LED in Verilog up and running, we can do an advanced version of the same project a binary counter using the LED's.Īlso this time I will be using the push button to increment the counter. Actually here is my preferred version of both an N-bit binary-to-gray and N-bit gray-to-binary conversion.
