Hello Nexys Video #2

Everything is the same to ProjectF as usual, except that I use all leds & combined 2-parts of the tutorials.

1. Verilog Code :

• I let the PWM module control leds instead of directly setting their states :

  pwm pwm_led_0 (.clk, .duty(dis ? 2 : (counter[0] ? 255 : 0)),   .pwm_out(led[0]));
  

• I manipulate them by dis and counter to control the led-duty.

• I use counter to store led old calculation :logic [7:0] counter;
