64?Bit Quartus II Software Cannot Simulate or Compile FIR Compiler

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

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.
