| Term | Definition |
| Generate parameter | A constant object whose type is the base type of the discrete range of a generate parameter specification. A generate parameter is declared by a generate statement. |
| Generic | An interface constant declared in the block header of a block statement, a component declaration, or an entity declaration. Generics provide a channel for static information to be communicated to a block from its environment. Unlike constants, however, the value of a generic can be supplied externally, either in a component instantiation statement or in a configuration specification. |
| Generic interface list | A list that defines local or formal generic constants. |
| Globally static expression | An expression that can be evaluated as soon as the design hierarchy in which it appears is elaborated. A locally static expression is also globally static unless the expression appears in a dynamically elaborated context. |
| Globally static primary | A primary whose value can be determined during the elaboration of its complete context and that does not thereafter change. Globally static primaries can only appear within statically elaborated contexts. |
| Group | A named collection of named entities. Groups relate different named entities for the purposes not specified by the language. In particular, groups may be decorated with attributes. |
| Guard expression | A Boolean-valued expression associated with a block statement that controls assignments to guarded signals within the block. A guard expression defines an implicit signal GUARD that may be used to control the operation of certain statements within the block. |
| Guarded assignment | A concurrent signal assignment statement that includes the option guarded, which specifies that the signal assignment statement is executed when a signal GUARD changes from FALSE to TRUE, or when that signal has been TRUE and an event occurs on one of the signals referenced in the corresponding GUARD expression. The signal GUARD must be one of the implicitly declared GUARD signals associated with block statements that have guard expressions, or it must be an explicitly declared signal of type Boolean that is visible at the point of the concurrent signal assignment statement. |
| Guarded signal | A signal declared as a register or a bus. Such signals have special semantics when their drivers are updated from within guarded signal assignment statements. |
| Guarded target | A signal assignment target consisting only of guarded signals. An unguarded target is a target consisting only of unguarded signals. |
