Architecture Control Logic Function Instantiation Example for Verilog HDL
You can instantiate Altera-provided logic functions from the alt_mf library, which includes the a_8fadd, a_8mcomp, a_8count, and a_81mux functions, in Verilog HDL designs. Altera provides behavioral Verilog HDL descriptions of these functions.
The following example shows an 8-bit counter that is instantiated using the a_8count function. Because Verilog HDL is case-sensitive, be sure to use uppercase letters for all of the macrofunction's module names and port names.
