Simulating a PWM waveform with varying duty-cycle
I found the following trick here: http://www.mikrocontroller.net/topic/100578(German only):
Add a voltage source to your schematic. Change it to an "arbitrary behavioral voltage source" by right-clicking on the symbol while simultaneously holding down the CTRL-key. Change the Prefix from "V" (standard) to "B" (behavioral). You can alternatively add a behavioral voltage source (BV) or current source (BI) directly....
