Why can't my own coefficient be used by the FIR compiler GUI?

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

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.

Resolution

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.
