SigmaStudio 3.5: FP Filter Table Generator behaviour

Hi,

I tried to use the Fixed-Point Table Generator in Sigma Studio 3.5 build 7 Rev 912 (== latest release).

 

Please have a look at the attached screenshot. Is this the correct behaviour when I try to generate filter coefficients?

I don't think so ;-)

 

Why is a Q1.15 FP value uncompatible? If this FP data format is allowed to enter by the tool, it shall generate the coefficients.

So, I would like to rank this behaviour as an error/bug.

 

BR,
