    I use a 555 to gen pwm signals over 200KHZ. Unless yours is a lot higher it shouldn't be a problem. Since the software is open source, I'd just get a copy and modify it for a pwm output. As a suggest,u could use a rtl model to construct the PWM circuit,it's quite simple as you use the 74series circuit,in my view, maybe nobody will take a look to check out the circuit. I have download the flowcode v4 and run the example, but when it connects to oscilicope, the waveform always change in the same period time.

    Regards,

    use 555 i.c or make a internal circuitry using pspice software and compare it with pin configuration of ne555. short 7 and 6 terminals and add a capacitor to this shorted terminals to 1 tern=minal and ground it.and short 4 and 8 terminals and coonect this 4,8 to 6,7 via a resistor apply trigger input to 2 terminal and modulating input to 5th terminal observe output at 3rd terminal w.r.t ground it works
