The Quartus II Compiler can create CSLA logic automatically during
design processing. Alternatively, the designer can create CSLA logic
manually during design entry. Parameterized functions such as library of
parameterized modules (LPM) and DesignWare functions automatically
take advantage of carry chains for the appropriate functions.
