After inserting the code, save and close the VHDL file. At the design hierarchy
explorer, you should see a mark at the left of the
Hex2LED module icon. It means the VHDL file is modified outside the tool and need to be analyzed. Invoke
Module -- Analyzed Module
(F4) to analyze the VHDL file. The
mark should be changed to
mark as before.
