The problem is that there is a paragraph that contains specifications for value parameters and for type parameters. It doesn't belong in either section. Currently it is in the section on type parameters. This is definitely a bad place, since most of the paragraph is about value parameters. And since it is talking about the type of a value parameter, this will get confused with the type that is the value of a type parameter. The paragraph needs to be broken into two separate parts, so that each part can be put into the relevant subclause. The paragraph in question reads: "In an assignment to, or override of, a parameter without an explicit type declaration, the type of the right-hand expression shall be unsized, real or integral. If the expression is real, the parameter is real. If the expression is integral, the parameter is a logic vector of the same size with range [size-1:0]. In an assignment to, or override of, a parameter with an explicit type declaration, the type of the right-hand expression shall be assignment compatible with the declared type. In an assignment to, or override of, a type parameter, the right-hand expression shall represent a data type." The first part, which belongs in subclause 6.3.1.1, is: "In an assignment to, or override of, a parameter without an explicit type declaration, the type of the right-hand expression shall be unsized, real or integral. If the expression is real, the parameter is real. If the expression is integral, the parameter is a logic vector of the same size with range [size-1:0]. In an assignment to, or override of, a parameter with an explicit type declaration, the type of the right-hand expression shall be assignment compatible with the declared type." The second part, which belongs in subclause 6.3.1.3, is just the last sentence: "In an assignment to, or override of, a type parameter, the right-hand expression shall represent a data type." It might be reasonable to merge this single-sentence paragraph with the single-sentence paragraph following it. They are somewhat related. So at a minimum, the first part of this paragraph needs to be moved to somewhere in subclause 6.3.1.1. I don't know whether it should become paragraph 2 or paragraph 3 in that subclause. Some wordsmithing would make the paragraphs flow better after separation. However, moving the first part into the right subclause is the most important part.
