[myhdl-list] Third-party modules?

[garyr <ga...@fi...>]

One of the entries in the MyHDL Frequently Asked Questions states that
third-party modules may be instantiated by using "user-defined code to
replace a MyHDL module by a corresponding instantiation".  My attempts
at this have not been successful. Could someone point me to an example?

Thanks in advance for your replies.
