Clear box supported megafunctions

The cbx.lst file, which is located in the \quartus\libraries\megafunctions directory, contains a list of clear box supported megafunctions. The cbx.lst file lists megafunctions using their corresponding clear box DLL name, which is required to use with the clear box command-line tool.

Each line in the cbx.lst lists a single megafunction and its corresponding clear box generator DLL. For example, the single-clock FIFO megafunction, scfifo, corresponds to the cbx_scfifo.dll clear box generator DLL. Clear box generator DLL names and the .dll extension are supported on all platforms.
