High-Level Architecture - 1.0 English

The high level block diagram for the Simulation Traffic Generator is shown in the following figure.

Test Sequence Library

This module generates the AXI request transaction objects based on the user configuration from the Vivado IDE.

Predefined Pattern

The Predefined Pattern allows you to generate simple custom traffic that can be configured in the AMD Vivado™ IDE.

User Defined Pattern

The User Defined Pattern allows you to write your own sequences to generate complex custom traffic using CSV input format.

Bandwidth Controller

This module calculates the transaction start delay based on the configured bandwidth settings. It is set on the transaction object. The updated transaction object is sent to the XVC module from the AXI Master BFM module.

Driver

This module uses the BFM transaction object to drive the AXI request on the AXI interface.

Monitor

The Monitor module collects the AXI request and AXI response details from the interface to create the complete transaction object. For each AXI request, the monitor creates a transaction object that has request and corresponding response information. These transaction objects are used on the Data Integrity Checker module to do data comparison.

Protocol Checker

The Protocol Checker module checks the protocol violation of AXI requests and AXI responses on the interface.

Data Integrity Checker

The Data Integrity Checker module collects the complete write transaction object from the monitor and stores the Write data into the internal sparse memory (associative array) with the AXI address as array index. When the complete read transaction object is received, the data integrity is evaluated by comparing the read data against the written data.

Traffic Shaping

The Traffic Shaping module is used to synchronize the traffic across the TGs in the design.

Debug

For ease of debugging, the Debug module prints information such as the sent request count, received response count, and error/warning condition messages.

Status Reporter

The Status Reporter module generates the test status report that consists of test configuration details and test pass/fail information. It is printed in the simulation log at end of simulation.
