Hello all

I use PSIM example "Buck Converter with Current Feedback (for F28069M DSP) to test PIL block function.

image(I add red circle circuit to test sin and cos function)

The result of IL and Vm between simcoder and PIL is the same.

However sin and cos waveform is quite different.

Can anyone tell me how to solve this problem?

thanks a lot

    Hi Hallay,

    We need to see the PIL block settings. Also, when using an instaspin enabled processor you need to check this box, this impact the memory location for the sin lookup tables used.
