Overview

Gold standard for PLB device for your IP, SoC and system-level design verification.

In production since 2011.

This Cadence® Verification IP (VIP) supports the IBM PLB standard. It provides a mature, highly capable compliance verification solution that supports simulation, formal analysis, and hardware acceleration platforms, making it applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP for PLB is compatible with the industry-standard Universal Verification Methodology (UVM), runs on all leading simulators, and leverages the industry-standard Cadence Memory Model core architecture, interface, and use model. The PLB VIP supports DCR, PLB4, and PLB6, for core, devices, and bus controller.

Supported specification: PLB4 and PLB6 Specifications - IBM confidential.
