    Hello,

    I need to create an voltage source that can generate a PWM specifications as shown below.

    Voltage level : 12V
    0-2s : 100KHz frequency with 2 % dutycycle
    2s-4s : duty cycle should slowly increase to 100% by 4s

    I have tried creating a PWL file with time and Voltage using VPWL File.., as
    0 12
    0.0000002 12
    0.000000201 0
    0.00001 0
    0.000010001 12
    0.0000102 12
    0.000010201 0
    0.00002 0

    However i am ending up with a huge data.., i have no idea how to use VPWL n time source.

    Can any one let me know how to do this in a simple manner.

    Thanks,
    Lakki.
