4. Functional Description
The SerialLite II MegaCore function consists of parameterized logic and a
parameterized testbench. The following sections detail the various possible
configurations and things you should consider when deciding how to configure the
link. Figure 4–1 shows a block diagram of the SerialLite II MegaCore function.
f Refer to Chapter 5, Testbench for more information on the test bench.

SerialLite II
Interface
As shown in Figure 4–1 , the SerialLite II MegaCore function is divided into two main
blocks: a protocol processing portion (data link layer) and a high-speed front end
(physical layer). The protocol processing portion features Atlantic FIFO buffers for
data storage or clock domain crossing, as well as data encapsulation and extraction
logic. The high-speed front end contains a link state machine (LSM) and
serializer/deserializer (SERDES) blocks. The SERDES blocks contain optional high-
speed serial clock and data recovery (CDR) logic implemented with high-speed serial
transceivers.
Interface Overview
The SerialLite II MegaCore function has two interfaces, the Atlantic interface and a
high-speed serial interface.
