Abstract

Methods and apparatuses are disclosed for creating a parameterized interleaver/de-interleaver megafunction for use in an electronic design, where the interleaver/de-interleaver megafunction requires specific setting of at least one variable parameter value. The method includes presenting a user with the opportunity to specify an adjustable parameter value for at least one interleaver/de-interleaver parameter. The specified parameter value then is received and a suitable interleaver and/or de-interleaver system is generated.
