This error message is from the code generation script of ReSim. The assertion 
fired since a "pcie_if" portmap has already been created. This is because ReSim 
does not automatically clean up global variables from previous runs. 

To clean up ReSim workspace, users can add 

ReSim::rsv_cleanup;

at the beginning of their code generation scripts (e.g., auto_generation.tcl) 
to make sure always starting from a clean workspace. 

Alternatively, users can also manually call this function in the Tcl 
interpreter that executes the code generation scripts. For example

ModelSim> ReSim::rsv_cleanup;

The last thing you can do is to restart your Tcl interpreter or ModelSim 
software.
