The other form of the GENERATE statement is the IF-scheme. This
scheme allows for conditional creation of objects. One obvious
difference between this scheme and the FOR-scheme is that all the
objects created do not have to be the same. While this IF statement
may seem similar to the IF-THEN-ELSE construct in behavioral VHDL, the
IF-scheme does not allow the use of ELSE or ELSIF branching.
The syntax for the IF-scheme GENERATE statement is shown in this
slide. The boolean expression of the IF statement can be any valid
boolean expression.
