Mentor Graphics Library of Questa Multi-view Verification Components Supports HDMI

Mentor Graphics Corporation announced that the Questa® Multi-view Verification Components (MVC) library now supports HDMI (High-Definition Multimedia Interface), a compact audio/video interface for transmitting uncompressed digital data. The Questa MVC library helps speed up functional verification of integrated circuits (ICs) incorporating HDMI interface logic, and drastically improves verification coverage for today’s complex multi-media platforms.

Lowering the Barriers to Mixed-abstraction Verification

The complexity of today’s SoC verification environments often requires designers to spend valuable time building and verifying multiple, and usually incompatible, verification models of a single block to support system-level, TLM-level and RTL-level verification. This lack of consistency prevents teams from easily moving up and down in abstraction and maximizing verification effectiveness.

Mentor’s Questa Multi-view Verification Components can connect to any level of abstraction from system to gates – ensuring consistent model behavior and giving the verification team more options to improve performance and increase coverage. The multi-view technology greatly reduces debug time through recognition of protocol stacks. This allows simulation results, from RTL verification, to be viewed as sequences of initiated transactions and responses, with the RTL signal activity correlated to a higher level transaction view of activity.

Each protocol, such as the HDMI, supported by the Questa MVC library includes a verification plan with full coverage metrics that integrates with the Questa Verification Management system. The verification plan easily incorporates into hierarchical full-chip verification plans. Questa Verification Management provides visibility into the status of the verification process by providing correlation of coverage metrics to the verification plan.

“The MVC library, which is written in SystemVerilog, supports OVM 2.0 with stimulus generation, reference checking, monitoring and functional coverage for popular protocols such as HDMI,” said Stephen Bailey, director of product marketing for the Design Verification Technology Division of Mentor. “This enables fast development of tests for all aspects of standard protocols for directed and constrained-random verification environments.”

Availability

Questa MVC support for HDMI is available immediately.

Questa Functional Verification Platform

The Questa functional verification platform combines high performance and high capacity and comprehensive verification capabilities Assertion-based Verification (ABV), intelligent testbench automation, Multi-view Verification Components (MVC), and Coverage-driven Verification (CDV) are supported natively by the Questa platform’s high-performance assertion engine; a modern, high-performance constraint solver; and extensive functional coverage features, including verification management leveraging the Unified Coverage Database (UCDB). Verification of low power design functionality can be proven in an RTL environment with power-aware functional verification. This full set of advanced verification functionality is enabled by a flexible Open Verification Methodology (OVM 2.0) that delivers unrivaled language and feature support in any design and verification flow.
