New ContributorQuestion with creating LED Toggle
Hello,
I am learning Verilog for the first time, and following some examples in a book. I am using the Intel Cyclone 10LP Evaluation Kit. The current example is to create a design which will toggle the state of an LED on the falling edge of a switch signal.
I've written the Verilog in Quartus and I think I have my clock, and pins configured correctly. However, the state of my LED will not change and I am lost on what to do for troubleshooting.
I have tried configuring other LEDs to the flip flop outputs to debug, but they flip flop outputs do not change state.
Could I receive some assistance on how to work through this.
I have attached my Verilog and the RTL viewer of what I have programmed.
Please let me know anything else I should attach.
module FlipFlopToggle( input i_Clk, input switch_1, output led_1); reg r_led_1 = 1'b0; reg r_switch_1 = 1'b0; always @(posedge i_Clk) begin r_switch_1 <= switch_1; if(switch_1 == 1'b0 && r_switch_1 == 1'b1) begin r_led_1 <= ~r_led_1; end end assign led_1 = r_led_1; endmodule
