Error (10430): VHDL Primary Unit Declaration error at dspba_library_package.vhd(16): primary unit "dspba_library_package" already exists in library "project name" and Error (10430): - Error (10430): VHDL Primary Unit Declaration error at dspba_library_package.vhd(16): primary unit "dspba_library_package" already exists in library "project name" and Error (10430): Description You may receive below error messages if the design consists of FIR II MegaCore® and Floating Point hardware 2 component in Qsys system. Error (10430): VHDL Primary Unit Declaration error at dspba_library_package.vhd(16): primary unit "dspba_library_package" already exists in library "project name" and Error (10430): VHDL Primary Unit Declaration error at dspba_library.vhd(17): primary unit "dspba_delay" already exists in library "project name" Resolution To work around this issue: 1. User can manually delete one of the assignments that contain "dspba_library_package.vhd" and "dspba_library.vhd" in the .qip file that generated by Qsys. 2. Another work around without manual intervention is that: a) Move the dspba_library.vhd and dspba_library_package.vhd from the following directory up one level. /../ip/altera/altera_nios_custom_instr_floating_point_2/altera_nios_custom_instr_floating_point_2_multi/FPAddSub b) Edit the following .tcl file by delete the FPAddsub/ that in front of dspba_library.vhd and dspba_library_package.vhd. /../ip/altera/altera_nios_custom_instr_floating_point_2/altera_nios_custom_instr_floating_point_2_multi/fpoint2_multi_qsys_hw.tcl Example after modification: set vhdl_filelist [list fpoint2_multi.vhd \ fpoint2_multi_datapath.vhd \ dspba_library_package.vhd \ dspba_library.vhd \ FPAddSub/FPAddSub.vhd \ FPDiv/FPDiv.vhd \ FPMult/FPMult.vhd \ IntToFloat/IntToFloat.vhd \ FloatToInt/FloatToInt.vhd \ FPSqrt/FPSqrt_safe_path.vhd \ FPSqrt/FPSqrt.vhd ] c) After above modification, please regenerate the Qsys and compile the design by using Quartus® II software . This issue will be fixed in Quartus II software version 15.0.
