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:

Sequential Statements: if-then-else general format: example: if (condition) then if (S = “00”) Any VHDL concurrent statement can be included in a. GENERATE statement, including another GENERATE statement. Two ways to apply.

Bokens mål är att lära ut VHDL, samt ge kunskap om hur man effektivt använder VHDL för att konstruera elektroniksystem med dagens utvecklingsverktyg.

2018-02-21 You are probably using an IF statement in the architecture body (which is a concurrent region). That's illegal. You need to put a process around it, so that it is in a sequential region (code is not tested!): process (seq, CNT_RESULT) if (SEQ = "000001") and (CNT_RESULT = "111111") then output<= '1'; CNT_RESET <= '0'; else output<='0'; end if; The If-Then-Elsif-Else statements can be used to create branches in our program. Depending on the value of a variable, or the outcome of an expression, the program can take different paths.

There are three keywords associated with if statements in VHDL: if, elsif, and else. Note the spelling of elsif! The if statement in VHDL is a sequential statement that conditionally executes other sequential statements, depending upon the value of some condition. An if statement may optionally contain an else part, executed if the condition is false. If a signal is conditionally assigned to itself, latches may be inferred. Whats New in '93 In VHDL -93, any signal assigment statement may have an optinal label.

If statements are used in VHDL to test for various conditions. They are very similar to if statements in other software languages such as C and Java. There are three keywords associated with if statements in VHDL: if, elsif, and else. Note the spelling of elsif!
