Best-in-class Arm® AMBA® Best-in-class Arm® AMBA® Distributed Translation Interface (DTI) Protocol Verification IP (VIP) for your IP, SoC, and system-level design testing.

Cadence provides a mature and comprehensive Verification IP (VIP)for theDistributed Translation Interface (DTI) specification, which is part of the Arm®AMBA®family of protocols. Incorporating the latestprotocol updates, the Cadence®Verification IP for DTI provides a complete bus functional model (BFM), integratedautomatic protocol checks, and coverage model.Designed for easy integration intestbenches at IP, system-on-chip (SoC), and system levels, the VIP for DTI helps youreduce time to test, accelerate verification closure, and ensure end-product quality. Cadence provides a solution for interconnect verification that verifies the correctness and completeness of data. The VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Supported specification: AMBA® DTI r0p0 Edition 3. AMBA DTI Issue F Update.

Product Highlights

  • Supports seamless integration in SystemVerilog, UVM, OVM, e, and SystemC® verification environments
  • Generates constrained-random bus traffic with predefined error injection
  • Comprehensive checking model
  • Could be used as standalone or with AXI-Stream as transport layer
  • Callbacks access for transaction modification, scoreboarding, and debugging
  • Dynamic activation to enable setting the VIP as active/passive during run time
  • Provides extensive System Verilog coverage

Key Features

The following table describes key features from the specifications that are implemented in the VIP:

Feature Name


Bypass Translation Mode Support

  • No translation happens via the TCU DTI VIP. Physical address will be the same as the Virtual address, and default attributes configured are used

Connect and Disconnect Message Group

  • The connection and disconnection of the DTI-TBU protocol channel

DTI-TBU Caching Module

  • The TBU implements a cache model in which translation response information is cached depending upon its intended function

Invalidation and Synchronization Message Group

  • Invalidation operations fo the TCU to indicate to the TBU that certain information must no longer be cached

Page Table Walk Support

  • TCU does a Page Table walk to determine the Physical address. User can load the page table entries through back door write

Random Mode Support

  • Translation request will be responded with random data in response

Register Access Message Group

  • The DTI TBU provides implementation defined registers, which can be accessed using these messages

Translation Request Message Group

  • The DTI-TBU translation requests messages to enable the TBU to find the translation for a given transaction or prefetch a translation

Simulation Test Suite

VIP comes along with a testsuite of scenarios for easy VIP evaluation and deployment.
