In this post, we have introduced the conditional statement.The IF-THEN-ELSE is a VHDL statement that allows implementing a choice between different options. 2020-04-03 · Test for less than and less than or equal. These operators check the relation for the given data A and B. In the case of less than ‘<‘, if in the given data A is less than but not equal to B, the result is a boolean true. And if A is greater than or equal to B, the result is a boolean false. The
VHDL executes if statements sequentially with cascading enables driving the output of your various conditional statements. All of the conditions
Let’s take an example, is we have if a_in (0) vector equals to 1, then encode equals to 000. See for all else if, we have different values.

A decoder that has two inputs, an enable pin and four outputs is implemented in a CPLD using VHDL in this part of the VHDL course. This 2 to 4 decoder will switch on one of the four active low outputs, depending on the binary value of the two inputs and if the enable input is high. History of VHDL. VHDL was developed by the Department of Defence (DOD) in 1980.
VHDL syntax is specified in an Extended Backus Naur Form and semantics specified by the standard's descriptive text.
