Slide 25 of 43
The second form of the GENERATE statement is the IF-scheme. This scheme allows for conditional generation of concurrent statements. One obvious difference between this scheme and the FOR-scheme is that all the concurrent statements generated do not have to be the same. While this IF statement may seem reminiscent to the IF-THEN-ELSE constructs in programming languages, note that the GENERATE IF-scheme does not provide ELSE or ELSIF clauses.
The syntax of the IF-scheme GENERATE statement is shown in this slide. The boolean expression of the IF statement can be any valid boolean expression.
