When I run simulation of a rapidio qsys,there is a error occures,but why it is happening?

When I run simulation of a rapidio qsys,there is a error occures,as this:

Info: Start Nativelink Simulation process

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
