5.1i CORE Generator - Error: "Improper coefficient value -.015 for initialization radix/Number of coefficients not equal to the number of taps"

Description

Keywords: 4.2i, 5.1i, COREGen, improper, coefficient, value, radix

Urgency: Standard

General Description:
In CORE Generator, when I add a COE file to a core that requires initialization (such as the DA FIR filter), the following errors are reported:

"Improper coefficient value -.005300 for initialization radix."
"Number of coefficients not equal to the number of taps."

Solution

This error is the result of an incorrect .coe file format. Decimals cannot be present in coefficients -- integers must be used.

Please see (Xilinx Answer 5366) for information on normalizing your coefficients to include integer values.
