The if statement in VHDL is a sequential statement that conditionally executes other sequential statements, depending upon the value of some condition. An if statement may optionally contain an else part, executed if the condition is false.

Case Statement - VHDL Example. 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. They are useful to check one input signal against many combinations.

message on the standard output. The concurrent statements in VHDL are WHEN and GENERATE. Besides them, assignments using only operators (AND, NOT, +, *, sll, etc.) can also be used to construct code.

Notes. All statements within architectures are executed concurrently. While it is possible to use VHDL processes as the only concurrent statement, the necessary overhead (process, begin, end, sensitivity list) lets designer look for alternatives when the sequential behavior of processes is not needed.
