ModelSim (MTI, MXE) - ERROR: ../../../<logiblox_module.v>: Instantiation of 'X_OR' failed (design unit not found). (Verilog)

Description

Keywords: LogiBLOX, SIMPRIM, Verilog, ModelSim, Vlog

Urgency: Standard

General Description:
When I simulate Verilog LogiBLOX modules using ModelSim Vlog, several of the following types of error messages are issued:

ERROR: ../../../<logiblox_module.v>: Instantiation of 'X_OR' failed (design unit not found)

解决方案

Please note that for Verilog simulation, the LogiBLOX modules use the SimPrim library. You must include the SimPrim-based libraries when simulating LogiBLOX modules. In addition to the SimPrim library, if you have instantiated cells from the device library, then the UniSim library must also be included:

vsim -L simprims_ver -L unisims_ver test

Please see (Xilinx Answer 2561) for information on mapping the Xilinx Verilog libraries.
