It’s a more elegant alternative to an If-Then-Elsif-Else statement with multiple Elsif’s. Other programming languages have similar constructs, using keywords such as a switch, case, or select. Among other things, Case-When statements are commonly used for implementing multiplexers in VHDL. Continue reading, or watch the video to find out how!

Page 3. Case statement: 2-1 Mux mux: process begin statements must be completely specified or VHDL compiler . Before they can be used, variables must be declared with a variable declaration statement, as in the following example: variable first_var : integer; variable Aug 83 Contract for development of VHDL. • Aug 85 Dec 87 IEEE Standard VHDL (1076-1987) approved. • Jun 90 Concurrent signal assignment statement. Only one type of conditional statements is allowed as concurrent which are shown here. 2.1 Conditional Signal Assignment.

The CASE statement is generally synthesisable. With repeated assignments to a target signal, it willsynthesise to a large multiplexer with logic on the select inputs to evaluate the conditions for the different choices in the case statement branches.

The syntax is demonstrated in the example below. The VHDL Case Statement works exactly the way that a switch statement in C works.

In addition, there is a sequen- tial statement that is unique to hardware modeling languages, the signal assignment statement. This is similar to variable

VHDL is a Hardware Description Language that is used to describe at a high level of Sequential conditional statement. Concurrent conditional statement. The concurrent conditional statement can be used in … In this code, the with, select and when VHDL keywords are used. The line with SEL select sets up SEL as the signal that is evaluated by the when statements that follow. 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 If statements may be used to specify conditional assignments or state transitions in a finite state machine: case READ_CPU_STATE is when WAITING => if CPU_DATA_VALID = '1' then CPU_DATA_READ <= '1'; READ_CPU_STATE <= DATA1; end if; when DATA1 => -- other branches of the case statement end case; Synthesis Issues. We use the when statement in VHDL to assign different values to a signal based on boolean expressions.

This is similar to variable noticed that VHDL has two forms of statements: concurrent and sequential. Concurrent statements take place in the architecture body. A concurrent statement ARCHITECTURE architecture_name OF entity name IS. -- declare some signals here.

A conditional assignment statement is also a concurrent signal assignment statement. target <= waveform when choice; -- choice is a boolean expression target <= waveform when choice else waveform; sig <= a_sig when count>7; sig2 <= not a_sig after 1 ns when ctl='1' else b_sig; "waveform" for this statement seems to include [ delay_mechanism ] See sequential signal assignment statement When a wait statement is encountered, the process in which appears that statement suspends.
