Remember that you have to scale each resistor divide ratio to match the FS coefficients...Ok so I set up the sources with the following frequencies, and got this:

6283

12566

18849

25132

Also, when I use a simple Excel spreadsheet to plot the FS function you are given, it's closer to an inverse sawtooth instead of a sawtooth waveform. And of course it doesn't include the offset and scaling yet to give you the 0-5V sawtooth waveform that you are asked to produce with your circuit:

When I use the FS from Wikipeda for a forward sawtooth waveform (including the offset and scaling for the Amplitude = 5V), it looks a lot closer once the initial startup phase is done...

Is there some way to verify with the instructor or TA whether that is the right FS that they want you to use in the problem statement?
