Hello, I am trying to create a testbench for a mips processor in VHDL. It compiles fine in quartus and in modelsim but when I try to start the simulation I get this error.
* Error: (vsim-3732) D:/Quartus/4712labvhd/top_level.vhd(169): No default binding for component instance 'UUT_CON'.
# The following component port is not on the entity:
# IR31_to_26
Anything Helps. The first bit of code is the testbench itself and the next is the top level entity that I use inside.
