Chapter 3: Functional Description
Interfaces & Signals
For Stratix II devices, you have the following three options for the constraints:
3–19
Dedicated top and bottom I/O pins, which gives the highest performance.
Migratable DM, DQ, and DQS pin constraints on all sides of the device, which
allows you to migrate your design to a migration device at a later stage, and gives
less pins.
Non-migratable pin constraints, which give much greater flexibility and a greater
number of available pins on all sides of the device.
Interfaces & Signals
This section describes the following topics:
Interface Description
This section describes the following local-side interface requests:
1
These interface requests are for the native interface. For information on the
Avalon-MM interface, refer to the Avalon Interface Specifications .
The native interface is a superset of the Avalon-MM interface. The native interface has
the following additional signals. These signals, which are not part of the Avalon-MM
interface, provide extra information and control for the native interface:
local_rdvalid_in_n
local_init_done
local_refresh_req
local_refresh_ack
local_wdata_req
f
For information on the datapath interface, refer to “Datapath” on page 3–4 .
