They can be used inside an if statement, a when statement, and an until statement. One important note is that VHDL is a strongly typed language. This means that when comparing two signals for their relationship, the signals that are being compared need to be of the same type.

VHDL-93 defines an unaffected keyword, which indicates a condition when a signal is not given a new assignment: label: signal = expression_1 when condition_1 else expression_2 when condition_2 else unaffected ; The IF-THEN-ELSE is a VHDL statement that allows implementing a choice between different options. When the number of options greater than two we can use the VHDL “ELSIF” clause. In case of multiple options, VHDL provides a more powerful statement both in the concurrent and sequential version: They can be used inside an if statement, a when statement, and an until statement. One important note is that VHDL is a strongly typed language.

We now turn our attention to a the VHDL process statement. one microsecond suspension, the process once again executes beginning with the IF statement.

The output of Similar to a “when/else” statement, the “if” statement incorporates priority-encoded logic. This means that the The Apart from missing "end if" and wrong assignment syntax, there are probably more VHDL errors. - don't use spaces in VHDL constants like "0 1 0", - the error message "expecting a concurrent statement" suggests, that the statement is misplaced in your code. It's only valid inside a process.

When used to model combinational logic for synthesis, a process may contain only one wait statement. If a process contains a wait statement, it cannot contain a sensitivity list. The process in Example 6.3, In this post we look at the use of VHDL generics and generate statements to create reusable VHDL code. This includes a discussion of both the iterative generate and conditional generate statements.. As with most programming languages, we should try to make as much of our code as possible reusable.This allows us to reduce development time for future projects as we can more easily port code from VHDL Sequential Statements These statements are for use in Processes, Procedures and Functions.

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!

Note the spelling of elsif! The example below demonstrates two ways that if If else statements are used more frequently in VHDL programming. If statement is a conditional statement that must be evaluating either with true or false result.
