AMBA ACE - Ensures cache coherency and data consistency in multi-core systems

Overview

AMBA ACE Verification IP (VIP) ensures correct cache coherency between processors and shared memory systems in SoC designs. It simulates complex scenarios like cache sharing, eviction, and invalidation to ensure protocol compliance and optimized system performance.

The VIP is ideal for multi-core processors, high-performance computing, and real-time applications. It supports advanced features such as snooping and directory-based coherency, accelerating development and reducing debugging time in systems requiring high data integrity.

Key Features

  • Comprehensive Cache Coherency Verification: Verifies compliance with cache coherency protocols across multiple processors. Ensures the proper handling of cache states such as shared, invalid, and exclusive for seamless communication.
  • Support for Advanced Coherency Models: Validates both snoop-based and directory-based coherency protocols for effective data consistency across multi-core systems. Essential for maintaining high performance in complex designs.
  • Multi-Layer Interconnect Support: Simulates interactions across multiple interconnect layers to ensure accurate protocol compliance in SoCs. Verifies proper operation in systems with complex memory hierarchies and communication paths.
  • Coherency Transaction Coverage: Covers key coherency transactions like ReadUnique, WriteBack, and CleanShared. Validates these operations under various traffic scenarios to ensure correct data handling across cores.
  • Highly Configurable Test Environment: Offers a parameterized test environment that allows for customization of ACE configurations. Tailors bandwidth, latency, and coherency levels to match specific system requirements.
