Why does the Nios® V processor fail to generate HDL with an add_fileset_file error message in Quartus® Prime Standard Edition from Windows OS?

Description

Due to a problem in the Quartus® Prime Standard Edition Software versions 22.1, 23.1, and 24.1, the Nios® V processor might fail to generate HDL with an error message about add_fileset_file. This issue is present only on Windows OS.

Example error message:
Error: add_fileset_file: No such file <Nios V processor SystemVerilog file> while executing “add_fileset_file $current_sim/<Nios V processor SystemVerilog file> SYSTEM_VERILOG PATH $current_sim/<Nios V processor SystemVerilog file> $attr” 

This is because the Nios® V processor hw.tcl is calling add_fileset_file on an unsupported simulator. These unsupported simulators are referring to simulators that are not supported in Windows OS - Cadence Simulator and Synopsys VCS* and VCS MX.

Resolution

To work around this problem in the Quartus® Prime Standard Edition Software version 24.1, download and install the patches below.

This problem is currently scheduled to be resolved in a future release of the Quartus® Prime Standard Edition Software.

Additional Information

For information on the simulators’ supported platforms, refer to the Quartus® Prime Standard Edition User Guide: Third-party Simulation - Supported Simulators.
