Digital Subscriber Line Access Multiplexer (DSLAM) Example Design

Digital Subscriber Line Access Multiplexer (DSLAM) Example Design
};
5.0 Project Configuration / Modifying the Example
Design
This example design can be assembled with a variety of options, all of which are configurable in
the header files: project_config.h and system_config.h.
6.0 Testing Environment
The testing environment is the same as the execution environment - for details refer to Section 1.3
of this document.
7.0 Simulation Support (Scripts, etc.)
The three Developer WorkBench projects in this design can be run using the simulator within the
DWB. Test streams, foreign model DLLs, and the simulator scripts that support them, can be used
to exercise the projects by providing various network traffic inputs to the WorkBench applications.
7.1 Simulation for the Receive Processor Project
7.1.1 Initialization Scripts
The file dslam_proc_a.ind is the primary initialization script for the Receive Processor project. It
invokes all other simulator scripts, including the dslam_perf_proc_a.ind script and the test case
scripts described below. The primary functions performed by this script are:
• Memory Map Initialization
• Queue Descriptor Table Initialization
• Scratch Memory Initialization
• SRAM Task Message Area Initialization
• Scratch Task Message Area Initialization
• Fast Port Index Initialization in the Queue Descriptor Table
• Route Table Manager Initialization
• Hash Table Manager Initialization
• Route Additions to the Route Table
• Invocation of a Selected Test Case Script
• Start of Packet Reception
