They can only be used in combinational code outside of a process. A selected signal assignment is a clear way of assigning a signal based on a specific list of combinations for one input signal. The syntax is demonstrated in the example below. The VHDL Case Statement works exactly the way that a switch statement in C works. Given an input, the statement looks at each possible condition to find one that the input signal satisfies.

Using Conditional Signal Assignments (VHDL) When a Conditional Signal Assignment Statement is executed, each Boolean expression is tested in the order in which it is written. The value of the expression preceding a WHEN keyword is assigned to the target signal for the first Boolean expression that is evaluated as true.
