AMBA AXI3 Synthesizable Transactor

Overview

Key Features

• Compliant with the latest ARM AMBA AXI3 Protocol Specification.
• Supports AXI3 Master and Slave.
• Supports all AXI3 data and address widths.
• Supports all protocol transfer types, burst types, burst lengths, burst sizes and response types.
• Supports constrained randomization of protocol attributes.
• Separate address, data and response phases. Separate read and write channels.
• Support for burst-based transactions with only start address issued.
• Slave supports fine grain control of response per address or per transaction.
• Programmable wait states or delay insertion on different channels.
• Ability to inject errors during data transfer.
• Write strobe support to enable sparse data transfer on the write data bus.
• Narrow transfer support.
• Unaligned address access support.
• Ability to issue multiple outstanding transactions.
• Out of order transaction completion support.
• Protected accesses with normal/privileged, secure/non-secure and data/instruction
• Support for Write data phase before Write address phase.
• Ability to configure the width of all signals.
• Support for bus inactivity detection and timeout (configuration parameter and dynamic change of inactivity timer).
• Write data and read data interleaving support.
• Configurable write and read interleave depth.
• Programmable interleave size per transaction to allow fixed and variable data interleaving in a transaction.
• Atomic access support with normal access, exclusive access and locked access
• Programmable Timeout insertion.
• Rich set of configuration parameters to control AXI3 functionality.
• On-the-fly protocol and data checking.
• Notifies the testbench of significant events such as transactions, warnings, timing and protocol violations.
• Callbacks in master and slave for various events.
• Status counters for various events on bus.

Benefits

• Compatible with testbench writing using SmartDV VIP's
• All UVM sequences/testcases written with VIP can be reused
• Runs in every major emulators environment
• Runs in custom FPGA platforms
