Hi All I have designed a comparator. Now, I am trying to create a square input voltage pulse to check my propagation delay time. However, for some reason, it only shows the triangular input wave even though I tried to set my pulse to be square wave.
Below is my netlist. Could someone please give me some assistant?
Thanks
