ModelSim error on IP instantiation: (vsim-3033) Instantiation of 'MULTADDSUB36X36' failed. The design unit was not found.

Description:

This error can occur when the Simulation tool uses the wrong libraries for your design.

Solution:

Go to the ModelSim File menu, then select Source Directory...
Select the directory where your work library is located.
Then, go to the Simulate menu.
Locate the Libraries tab.
Click add then add the FPGA device library. Example: Certus-NX device library located at C:/lscc/radiant/3.1/modeltech/lib/lfd2nx
Re-run simulation.

If this does not resolve the issue, then please file a tech support ticket.
