.SPD file generation

I am trying to run the RTL simulation tool through Quartus Prime Standard Edition.

But it gives me following error in the nativelink_simulation.rpt

-----------------------------------------------------------------------------------------------------------------------------------------------------

Info: Start Nativelink Simulation process

executing command line: ip-make-simscript --nativelink-mode --output-directory=abcd_iputf_input --spd=C:/projects/abcd_restored/abcd1.spd --spd=C:/projects/abcd_restored/abcd2.spd --spd=C:/projects/abcd_restored/abcd3.spd --spd=C:/projects/abcd_restored/abcd4.spd --spd=C:/projects/abcd_restored/abcd5.spd --spd=C:/projects/abcd_restored/abcd6.spd

Error: You did not generate the simulation model files or you generated the IP file using an older version of MegaCore which is not supported by RTL NativeLink Simulation

Error: Regenerate the IP and simulation model files using the latest version of MegaCore for RTL NativeLink Simulation flow to function correctly

Error: NativeLink simulation flow was NOT successful

================The following additional information is provided to help identify the cause of error while running nativelink scripts=================

Nativelink TCL script failed with errorCode: NONE

Nativelink TCL script failed with errorInfo: Regenerate the IP and simulation model files using the latest version of MegaCore for RTL NativeLink Simulation flow to function correctly

(procedure "get_ip_info" line 1)

invoked from within

"get_ip_info $full_file_name"

(procedure "run_eda_simulation_tool" line 195)

-----------------------------------------------------------------------------------------------------------------------------------------

I have regenerated the IP and Simulation Models successfully . All files were updated except the .spd files.

I hope i could get some insight on how to regenerate the .spd files

Thank you
