Hello,

I am trying to using FIR core 6.2 version to interpolate a signal at 7.68MHz by 4. This is the error I get when I try to instantiate the core. Can anyone please share their thoughts on what this points to and suggest a solution?

ERROR:HDLCompiler:1316 -
"C:\~\ISE\ipcore_dir\tmp\_cg\_bbx\fir_compiler_v6_2\polyphase_interpolation.vhd" Line 5138: Index value <data_sym> is out of range [coef:data] of array
<ci_mem_if_addr_widths>

Thanks a ton!!

Hi,

just recheck your filter definitions.

There seems to be a mismatch between the provided  number of coefficients and the storage provided by the FIR core.

(Sometimes it's just some space, empty line or <CR><LF> too much in the Coefficient file)

Have a nice synthesis
