Here is a brief explanation of the keywords in the Coefficient File:
Component_name: Declares the name of the component.
Number_of_taps: Specifies the number of taps.
Radix: Specifies the base of the coefficient. (Radix=10 indicates that the coefficients are in base 10 (decimal) format; Radix=16 indicates that the coefficient is in hexadecimal format.)
Input_width: Specifies the input width.
Coef_width: Specifies the output width.
Output_width: Specifies the output width.
Symmetry: Specifies the symmetry of the filter. ("TRUE" indicates that the filter coefficients are symmetrical, "FALSE" means they are asymmetrical.)
Cascade: Specifies whether the cascade capability of the filter is enabled.
Trim_empty_rom: Trims out unnecessary logic associated with ROM modules. This option can save some resources by trimming out unused logic; however, use of this option may reduce the maximum output bit width.
