CoreAI

v2.0

ACM (Analog Configuration MUX) interface, Analog

Quads, and RTC (Real-Time Counter). The ACM interface,

within the AB macro, is used to control configuration of

the Analog Quads and RTC in the Fusion device. CoreAI

generates the control signals used by the ACM, including

its clock signal, which is generated by an internal clock

divider. The ACM clock divider is used to ensure that the

ACM interface is clocked at a frequency less than or

equal to 10 MHz (refer to "ACM Interface" on page 18

for details). For more details on the silicon features of

the AB macro, such as the Analog Quads, RTC, or ACM,

refer to the Fusion datasheet.

Several aspects of CoreAI can be configured using top-

level parameters (Verilog) or generics (VHDL). For a

detailed description of the parameters/generics, refer to

Table 4 on page 6.

The CoreAI block diagram is shown in Figure 1. A typical

application using CoreAI is shown in Figure 2.
