Every concurrent signal assignment, whether conditional or selected, can be modelled with a process construct, however. if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false.

Depending on the result of an expression, the program can take different VHDL Sequential Statements These statements are for use in Processes, Procedures and Functions. The signal assignment statement has unique properties when used sequentially. Sequential Statements ; wait statement ; assertion statement ; report statement ; signal assignment statement ; variable assignment statement ; procedure call statement ; if statement After watching this video you are able to use if else statement in VHDL.

The if statement is a conditional statement which uses boolean conditions to determine which blocks of VHDL code to execute. 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. 2011-07-04 Learn how to create branches in VHDL using the If, Then, Elsif, and Else statements.

Official name for this VHDL when/else assignment is the conditional signal assignment b <= "1000" when a = "00" else "0100" when a = "01" else "0010" when a = "10" else "0001" when a = "11" ; Combinational Process with Case Statement VHDL With Select Statement. When we use the with select statement in a VHDL design, we can assign different values to a signal based on the value of some other signal in our design. The with select statement is probably the most intuitive way of modelling a mux in VHDL. Nested IF-THEN-ELSE-END IF .
