Best-in-class HDMI Verification IP for your IP, SoC, and system-level design testing.

In production since 2011 on many production designs.

The Cadence® Verification IP (VIP) for HDMI provides a mature, highly capable compliance verification solution for the HDMI Protocol. The VIP for HDMI supports simulation and hardware acceleration platforms making it applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

The High-Definition Multimedia Interface (HDMI) is an audio/video (A/V) transmission protocol, which is omnipresent in consumer electronics, PC, and mobile products. HDMI supports two kinds of devices: SOURCE, which transmits A/V on HDMI cable, and SINK, which receives and decodes A/V.

Supported specifications: HDMI VIP supports HDMI Protocol versions 1.4b, 2.0a, and 2.1.
