Simulation Parameters
Padding Data into Memory Map
The ALTUFM_I2C megafunction uses the upper 8 bits of the UFM 16-bit word;
therefore, the 8 least significant bits should be padded with 1s, as shown in
Figure 7–41.

Simulation Parameters
In the ALTUFM megafunction, you have an option to simulate the OSCoutput port at
the maximum or the minimum frequency during the design simulation. The
frequency chosen is only used as the timing parameter for the Quartus II simulator
and does not affect the real MAX V device OSCoutput frequency.
