Multiple FIR Megafunctions

Honored Contributor II



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?
