Intel: An error occurred when running NativeLink simulation. Internal error: Failed to run ip-make-simscript

Quartus PrimeSimulation

Category: Tool
Tools: Quartus® Prime Standard Edition / Questa*-Intel® FPGA Edition
device:-

When running Questa* - Intel® FPGA Edition or Questa* - Intel® FPGA Starter Edition in NativeLink simulation from Quartus Prime Standard Edition (or Lite Edition), an Internal Error may occur as shown below.

pattern 1 s message (Left figure)	Internal error: Failed to run ip-make-simscript: <Date and time (Year.Month.Day.Hour:Minute:Second)> Error: Unrecognized switch <b>1</b> Check the NativeLink log file <project folder path>/<revision name>_nativelink_simulation.rpt for detailed error messages
pattern 2 s message (Right figure)	Internal error: Failed to run ip-make-simscript: <Date and time (Year.Month.Day.Hour:Minute:Second)> Error: Unrecognized switch <b>1</b> <Date and time (Year.Month.Day.Hour:Minute:Second)> Error: Unrecognized switch <b>2</b> Check the NativeLink log file <project folder path>/<revision name>_nativelink_simulation.rpt for detailed error messages

If you check the contents of <revision name>_nativelink_simulation.rpt displayed in the popup, you will find the following logs:

pattern 1

Error: NativeLink simulation flow was NOT successful

The causes and workarounds for this error are as follows:

	factor	Workaround
pattern 1	The sdp file for the IP* included in the project is not in the specified path. (*IP created using other than MwgaWizard Plug-In Manager)	Start the existing IP in edit mode and run HDL Generate to generate the spd file again along with the .sip.
pattern 2	The folder path where you generated the IP used in your design contains double-byte characters or spaces.	Please modify the path to be full-width or do not include spaces.

Then run the NativeLink simulation again.
