Hello,

I try to realize a Distributed Arithmetic Architecture with CoreGen (ISE 13.4 (lin64), FIR Compiler 5.0). The problem is, that when I creat the filter with CoreGen, instantiate it in an HDL-File and try to generate the programming file i get several warnings and in the end the design cannot be simulated and the number of occupied slices is very small.

That's how I try to do it:

Coregen 13.4 (lin64)

-> New Projekt
    Top-Level Source Type HDL
    Virtex 4 - XC4VSX25-FF668

-> New Source

-> IP (CORE Generator & Architecture Wizard)

    Digital Signal Processing -> Filters -> FIR Compiler 5.0

    all default settings except Filter Architecture (Distributed Arithmetic) and coefficients

-> Generate

-> Use created component in a HDL (see attachements)

-> Generate Programmingfile

It would be very nice if someone could help me

Hello again,

I have the same problem when I use ISE11.5 and ISE12.1 (FIR Compiler 5.0), but finally with ISE12.3 everything works fine. So my problem is solved by using another version, but I can not understand why it doesn't work with the other versions.

Regards
