Concurrent Statements
Concurrent Statements
- Execute statements in a concurrent manner.
- The "<=" operator refers to the signal assignment operator. The signal assignment operator signifies a transfer of data from the right-hand side of the operator to the left-hand side.
- Concurrent signal assignment statements will receive values of the expression (defined by a constant, signal, or a set of operators that operate on other signals).
Conditional Signal Assignments
Conditional Signal Assignments
- Concurrent signal assignment statements, seen before, associate one target with one expression.
- The term conditional signal assignment is used to describe statements that have only one target but can have more than one associated expression assigned to the target.
- Each of the expressions is associated with a certain condition. The individual conditions are evaluated sequentially in the conditional signal assignment statement until the first condition evaluates as true.
