Description
This error may occur in the Quartus® II software when you are:
- Converting a design originally created using the MAX PLUS® II software.
- Using library of parameterized modules (LPM) functions created in the Altera® Hardware Description Language (AHDL) in your design.
The error is caused because you are including inst.tdf files, which are created with the MegaWizard™-generated LPM files, in a Quartus II project. inst.tdf files are only for reference when instantianting LPM functions in a project. Remove these files in order to fix the error.
Similar errors will occur for VHDL and Verilog HDL if these files are added to the project.
