There are three dedicated paths between ALMs: Register Cascade, Carry-chain, and
Shared Arithmetic chain. Arria II GX devices include an enhanced interconnect
structure in LABs for routing shared arithmetic chains and carry chains for efficient
arithmetic functions. The register chain connection allows the register output of one
ALM to connect directly to the register input of the next ALM in the LAB for fast shift
registers. These ALM-to-ALM connections bypass the local interconnect.
shows the shared arithmetic chain, carry chain, and register chain interconnects.
Figure 2–13. Shared Arithmetic Chain, Carry Chain, and Register Chain Interconnects
The ALM directly supports an asynchronous clear function. You can achieve the
register preset through the Quartus II software’s NOT-gate push-back logic option.
Each LAB supports up to two clears.
Arria II GX devices provide a device-wide reset pin (DEV_CLRn) that resets all
registers in the device. An option set before compilation in the Quartus II software
enables this pin. This device-wide reset overrides all other control signals.
