AXI to UCIe Bridge IP
Design IP
Overview

SmartDV’s AXI to UCIe Bridge IP enables seamless integration between standard AMBA AXI-based SoC architectures and the emerging UCIe (Universal Chiplet Interconnect Express) ecosystem. Designed for advanced chiplet-based designs, this bridge facilitates high-bandwidth, low-latency communication across die-to-die interfaces, accelerating modular and scalable system development.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports key UCIe features such as protocol adaptation, data integrity, and flow control, making it ideal for next-generation multi-die systems.

Benefits
  • Robust AXI-to-UCIe Bridging – Seamlessly connects AMBA AXI interfaces to UCIe protocol across chiplets or dies using standard or advanced packages
  • Broad UCIe Version Support – Supports UCIe Specification v1.0, v1.1, and v2.0, ensuring compatibility with evolving multi-die ecosystems
  • Flexible Performance Scaling – Operates across 4 GT/s to 32 GT/s data rates and 500 MHz to 4 GHz clock frequencies, with support for 800 MHz sideband data
  • Customizable Lane and Bus Configuration – Configurable for 16, 32, or 64 lanes and data bus widths from 8 to 1024 bits for tailored bandwidth requirements
  • Advanced Streaming Protocol Support – Supports Raw, Standard 256B, Start/Header Flit Formats, and Latency-Optimized 256B formats with optional bytes
  • Comprehensive Sideband Messaging – Enables link training, parameter exchange, mailbox read/write configuration, and vendor-defined extensions
  • Reliable Data Transfer – Includes Flit CRC, Flit Retry, DLLP field checks, data link feature exchange, and link power management for robust operations
  • Highly Configurable AXI Integration – Compatible with AXI3 and AXI4; supports burst transactions, increment bursts, separate read/write channels, and optional support for multiple outstanding transactions
  • Power-Efficient Operation – Implements clock gating and handshake mechanisms to minimize power during idle or low-activity states
