Block Symbol File (.bsf) Definition

A symbol file (with the extension .bsf) created with the Quartus^® Prime Symbol Editor. You can read and edit a symbol, which represents a macrofunction, primitive, megafunction, or design file, in a Block Symbol File, and add the symbol to a Block Design File (.bdf) with the Symbol Editor. You can also specify the ports and parameters of a symbol. The Symbol Editor allows you to open Library Mapping Files (.lmf); however, you must make the read-only Library Mapping Files writable before you edit them.
