Overview

The CL_SDE example implements the FPGA custom logic used to generate the AFI to demonstrate the Virtual Ethernet Application. The CL_SDE demonstrates the following -

  1. Using the Streaming Data Engine (SDE) IP Block in your custom logic.
  2. Connectivity between the Virtual Ethernet Application and the SDE.
  3. Connectivity between the Shell and the SDE.
  4. Clocks and Resets for the SDE.
  5. Floorplanning and Implemention with the SDE including pipelining for AXI buses, resets etc.

Functional Description

The following functionality is implemented in the CL_SDE -

  1. Capability to loopback from H2C and C2H.
  2. Memory to store and read H2C packets for H2C functional testing
  3. AXI Stream Traffic Generator for C2H functional and performance testing
  4. AXI4 Traffic Generator for PCIM performance testing
  5. Configuration and Reset generation logic.
  6. Pipelining for PCIM and PCIS interfaces.

See SDE HW Guide for details about the functional description of the SDE.

Interfaces and Address Range

Interfaces

CL_SDE uses three interfaces from the Shell. The PCIS interface is used to provide connectivity between the Virtual Ethernet Application and the SDE. The OCL interface is used to provide connectivity between the host and all the test/control/utility blocks (except the SDE). The PCIM interfaces is used by the SDE to read and write to host memory.

Address Range

Software

The software is provided as part of the Virtual Ethernet Application.
