These statements allow you to perform step-by-step computations. Process Statements that describe purely combinational behavior can also be used to create combinational logic. VHDL-2008 makes the generate statement much more flexible. It is now allowed to use else and elsif. Also there is a case version of generate. This makes generate easier to use.

Component instantiation can be used to connect circuit elements at a very low level or most frequently at the top level of a design. VHDL written in this form is known as Structural VHDL. The instantiation statement connects a declared component to signals in the architecture. VHDL syntax requires an IF statement or a CASE statement to be written within a PROCESS block. A PROCESS is a construct containing statements that are executed if a signal in the sensitivity list of the PROCESS changes. VHDL code can, in some sense, be divided into concurrent and sequential code.

9. Select for execution one or more of the enclosed sequential statements. (if more than one sequential statement, use ';' at the end of each statement). ▫.

Whenever a given condition evaluates as true, the code branch associated with that condition is executed. This statement is similar to conditional statements used in other programming languages such as C. The If-Then-Elsif-Else statements can be used to create branches in our program.

Generate Statement - VHDL Example. Generate statements are used to accomplish one of two goals: Replicating Logic in VHDL; Turning on/off blocks of logic in VHDL; The generate keyword is always used in a combinational process or logic block. It should not be driven with a clock. VHDL case Statement The case statement operates sequentially and can only be used inside a sequential block of code such as a process.
