The documentation for the FIR Compiler II GUI in the Quartus® II software version 12.1 - 13.0, incorrectly describes the file format for the input coefficients.
The file should be constructed as follows:
- Coefficients within the same bank should be on the same row separated by a comma
- Every new bank should be on a new line
For example:
BANK0_COEFF_0,BANK0_COEFF_1,BANK0_COEFF_2,BANK0_COEFF_3
BANK1_COEFF_0,BANK1_COEFF_1,BANK1_COEFF_2,BANK1_COEFF_3
Note: Do not use carriage return at the end of the last line
This problem has been fixed for the Quartus II software version 13.0 SP1, and the documentation has been updated accordingly.
