ModelSim - # ** Error: (vcom-1141) Identifier "x_dsp48a1" does not identify a component declaration."

Description

When I run a simulation of a Xilinx design, I encounter the following error:

 

ModelSim - # ** Error: (vcom-1141) Identifier "x_dsp48a1" does not identify a component declaration."

 

This error is occurring on a simulation netlist generated by a Xilinx tool (NetGen).  


As a result, I do not have control over what is written into the netlist.

 

How can I resolve this error?

Solution

This error can occur if your pre-compiled simulation libraries have not been updated to match your current version of ISE Design Suite or ISE Foundation tools.

 

If using ModelSim XE, please visit the Xilinx Downloads page and install the latest ModelSim XE libraries for your ISE Design Suite or ISE Foundation release.

 

If using other editions of ModelSim, please use the Simulation Libraries Compilation Wizard (CompXlib) to pre-compile the simulation libraries for your current version of ISE Design Suite or ISE Foundation tools.
