I encounter the following error when I run a simulation using ISim:
ERROR:Simulator:19 - Instance /example_design/clkgen/ attempts to connect to a formal port named clk_in which does not exist in the instantiated module clkgen.
ERROR:Simulator:34 - Elaboration failed.
How can I resolve this error?
This error can occur if there is a port list mismatch between the declaration and instantiation of an entity/module.
To resolve this error, make sure that all the ports declared in the module/entity match exactly.
