Reply To: LibraryUnit adding scripts to simulate
LibraryUnit in this case is the name which you used with simulate, hence, either the name of your testbench or configuration that runs your testbench. Often, I try to make this the same as the TextCaseName, but it does not have to be.
In VHDL, LibraryUnit is an analyzed Design Unit and from the LRM,
A design unit is
either an entity declaration, an architecture body, a configuration declaration, a package declaration, a
package body, a package instantiation declaration, a context declaration, or a PSL verification unit. (13.1)
