The IIR “Text file (Annotated TF)” export from all our products contains parameter settings and raw biquad coefficients (at the FIR Creator sample rate).
Is this the QSYS IIR block you are using?
We can implement a Qsys specific CSV export in a future update. In the meantime, you can make a CSV by taking the FIR Creator TXT file and copying the coefficients into a CSV file. For example
IIR Mode: General Sampling Rate: 48000 Hz HPF_BUTTERWORTH, 100.000 Hz, Order 2 b0:0.9907866979404248 b1:-1.9815733958808497 b2:0.9907866979404248 a0:1.0000000000000000 a1:-1.9814885091445689 a2:0.9816582826171297
0.9907866979404248, -1.9815733958808497, 0.9907866979404248, 1.0000000000000000, -1.9814885091445689, 0.9816582826171297
