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. Essential VHDL for ASICs 69 Concurrent Statements - Process Statement The PROCESS statement encloses a set of sequentially executed statements. Statements within the process are executed in the order they are written. However, when viewed from the “outside” from the “outside”, a process is a single concurrent statement. Format: label: The type of the expression in the head of the case statement has to match the type of the query values.

Concurrent statements in a design execute continuously, unlike sequential statements … 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.

When the logic levels on SEL match one of the values to the right of one of the when statements, the signal to the left of that when statement will be assigned to the output Select Statement - VHDL Example Assigning signals using Selected signal assignment. Select statements are used to assign signals in VHDL. 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 if statement is generally synthesisable.
