The Altera Quartus II software includes sophisticated tools that fully utilize the
advantages of the UFM block in MAX V devices, while maintaining simple, easy-to-
use procedures that accelerate the design process. The following section describes
how the ALTUFM megafunction supports a simple design methodology for
instantiating standard interface protocols for the UFM block, such as:

This section includes the megafunction symbol, the input and output ports, and a
description of the MegaWizard Plug-In Manager options. Refer to Quartus II Help for
the ALTUFM megafunction Altera Hardware Description Language (AHDL)
functional prototypes (applicable to Verilog HDL), VHDL component declarations,
and parameter descriptions. You can access this megafunction from the Memory
Compiler directory on page 2a of the MegaWizard Plug-In Manager.
The ALTUFM MegaWizard Plug-In Manager has separate pages that apply to the
MAX V UFM block. During compilation, the Quartus II Compiler verifies the
ALTUFM parameters selected against the available logic array interface options, and
any specific assignments.

The ALTUFM_I2C megafunction features a serial, 8-bit bidirectional data transfer up
to 100 Kbits per second. With the ALTUFM_I2C megafunction, the MAX V UFM and
