| Term | Definition |
| Left of | When both a value V1 and a value V2 belong to a range and either the range is an ascending range and V2 is the successor of V1, or the range is a descending range and V2 is the predecessor of V1. |
| Left-to-right order | When each value in a list of values is to the left of the next value in the list within that range, except for the last value in the list. |
| Library unit | The representation in a design library of an analyzed design unit. |
| Linkage | One possible port mode. A design entity whose entity interface contains a port of mode linkage implies that the behavior of the design entity is not expressed in terms of VHDL semantics. |
| Literal | A value that is directly specified in the description of a design. A literal can be a bit string literal, enumeration literal, numeric literal, string literal, or the literal null. |
| Local generic | An interface object declared in a component declaration that serves to connect a formal generic in the interface list of an entity and an actual generic or value in the design unit instantiating that entity. |
| Local port | A signal declared in the interface list of a component declaration that serves to connect a formal port in the interface list of an entity and an actual port or signal in the design unit instantiating that entity. |
| Locally static expression | An expression that can be evaluated during the analysis of the design unit in which it appears. |
| Locally static name | A name in which every expression is locally static (if every discrete range that appears as part of the name denotes a locally static range or subtype and if no prefix within the name is either an object or value of an access type or a function call). |
| Locally static primary | One of a certain group of primaries that includes literals, certain constants, and certain attributes. |
| Locally static subtype | A subtype whose bounds and direction can be determined during the analysis of the design unit in which it appears. |
| Longest static prefix | The name of a signal or a variable name, if the name is a static signal or variable name. Otherwise, the longest static prefix is the longest prefix of the name that is a static signal or variable name. |
| Loop parameter | A constant, implicitly declared by the for clause of a loop statement, used to count the number of iterations of a loop. |
| Lower bound | For a range L to R or L downto R, the smaller of L and R. |
