This is not the bug. This kind of error pops up when extra spacing in coefficients. Just try to remove extra space and regenerate the core/block. please share the test case

 

check this one known issue

Re: integration with sysgen fdatool

Please use following functions to figure out the maximum and minimum coefficient value generated by FDATool : 

max(xlfda_numerator('FDATool')) 

min(xlfda_numerator('FDATool'))

 

Also check the coef width setting in FIR. From the error message, it seems the xlfda_numerator('FDATool') value is out of range. Please try to increase coef width, and see if it helps
