Overview

Cadence provides a mature and comprehensive Verification IP (VIP) for the ACE specification which is part of the Arm® AMBA® family of protocols. Incorporating the latest protocol updates, the Cadence® Verification IP for ACE provides a framework for system-level coherency, integrated automatic protocol checks, and coverage model. Cadence provides an integrated solution for interconnect verification that supports the verification of coherent interconnect and performance analysis that provides automated generation of testbenches. The VIP provides a mature, highly capable compliance verification solution making it applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP for AMBA ACE is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Supported specification: AMBA ACE-Lite, AMBA 5 ACE, AMBA 5 ACE-Lite, AMBA 5 ACE-LiteDVM interfacesת AMBA ACE issues F, G, and H.

SoC design: When a network-on-chip meets cache coherency

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To understand the issues at hand, it’s first necessary to understand the role of cache in the memory hierarchy.

Co-Designed Cache Coherency Architecture for Embedded Multicore Systems

In this paper, we present the round-robin method applied to baseline coherency protocol and initial analysis of one hybrid protocol that performs speculative requests when access patterns are detected. We also propose to manage patterns through a dedicated hardware component attached to each core of the processor.
