Overview

Best-in-class Arm SWD Verification IP (VIP) for your IP, SoC, and System-level Design Testing

The Cadence Verification IP (VIP) for SWD provides support for the Serial Wire Debug protocol, which is part of the Arm® Debug Interface Specification. It provides a highly capable compliance verification solution that supports simulation, formal analysis, and hardware acceleration platforms incorporating the latest protocol updates with integrated automatic protocol checks and a coverage model. Designed for easy integration in testbenches at IP, system-on-chip (SoC), and system levels, the VIP for SWD runs on all major simulators and supports SystemVerilog and e verification languages along with associated methodologies, including the Universal Verification Methodology (UVM) and Open Verification Methodology (OVM).

Supported specification: SWD v1 and v2 as per Arm Debug Interface specification v6.0 (ADIv6.0).
