Multiple FIR Megafunctions

812 Views

Hi,

I am trying to use multiple FIR filters on a Cyclone II. I current have 1 of 6 that compiles correctly.

When I compile with all the .qip files include i get this error.

Error (10430): VHDL Primary Unit Declaration error at auk_dspip_lib_pkg_fir_120.vhd(15): primary unit "auk_dspip_lib_pkg_fir_120" already exists in library "work"

But when i remove the duplicate libraries to remove this issue only the filter .qip that has the library is compiled.

I also tried just including the files generated by the megafunction but that didn't seem to work either.

Any one else ever work with multiple FIR filters in Quartus?
