In version 1.5.6 of SVEditor, I'm seeing problems with
included files when they are viewed in the editor whenever something other than a variable declaration is encountered. The attached example has a module called 'tb' thatincludes a file called 'inc.svh' that contains a simple initial block with a single $display in it. The problems window is empty, but there is an error marker on the initial line in inc.svh saying 'Invalid type name "initial"'.
It could be that there is some confusion when inc.svh is opened in the editor, and it is being interpreted as if it were a file that is being compiled directly with compilation-unit scope, not by being `included.
