Hi all Just a follow up email relating to Danny's email from a while ago.

The pfb_fir_real now includes mask parameters allowing the designer to choose adder implementation strategy (DSP48/Fabric core or behavioral HDL). This allows trading off performance and resource usage. The convert block mentioned has also been changed. Hopefully this makes life a little easier. I would recommend adding an extra unit of latency to your adder latency if using DSP48 as your adder implementation strategy. Regards Andrew
