64?Bit Quartus II Software Cannot Simulate or Compile FIR Compiler - 64?Bit Quartus II Software Cannot Simulate or Compile FIR Compiler Description The 64?bit Quartus II software software installation cannot generate a functional simulation model for any variation of the FIR Compiler and cannot compile the FIR Compiler, because it does not generate the expected netlist. When the software attempts to generate a FIR Compiler functional simulation model, the following error message displays: IP Functional Simulation Model Creation Failed. The following error was returned: Error: Node instance “fircore” instantiates undefined entity “< instance_name >_st” File When the software attempts to compile a design that includes a FIR Compiler instance, the following error message displays: Error: Node instance “fircore” instantiates undefined entity “< instance_name >_st” This issue affects all FIR Compiler variations. The FIR Compiler netlist is not generated. Resolution To avoid this issue, install and use the 32-bit Quartus II software.
