XST - "ERROR:HDLParsers:850 - .vhd Line xx. Formal port does not exist in Component ''."

Description

General Description:

When I analyze a VHDL design, the following error occurs:

"ERROR:HDLParsers:850 - <file>.vhd Line xx. Formal port <name> does not exist in Component '<entity>'."

Solution

This error occurs if the port name in the component declaration does not match the port name in the component instantiation.

To solve this problem, change the name so that the port declaration and instantiation match.
