When I try and generate a triangle waveform with a frequency above 200 Hz all I get is a constant value, 0, is it not possible to generate high frequency triangle pulses or is this just a bug in the software? I'm using the latest version of VisSim ecd.

    What is your sampling rate? It would have to be above 400 Hz to get anything approaching a triangle wave. What are you doing with the wave? Modulating a PWM? Please attach your diagram so we can comment further.

    Thank you, I completely forgot about changing the sampling rate.
