CIC Filter: Possible bug in Coregen?

Hi all,

I'm using the LogicCORE CIC filter (ISE 9.2.04) with a decimation of 100, 4 integrators and 2 delays. The input is 16 bits and the output is also 16bits (also tried to use full precision, 47 bits). The problem is that the output is gibberish, even when the input is a constant. This worked fine with ISE 8.2, what is wrong.

Best regards,

Sergio Rui Silva
