Overview

SmartDV’s Embedded DisplayPort Verification IP is a comprehensive solution for verifying the embedded display interface used in laptops, tablets, automotive displays, and other embedded panel applications. Fully compliant with VESA eDP v1.5a and backward compatible with eDP 1.5, 1.4b, 1.4, and 1.3, and based on DisplayPort specifications 1.2 through 2.0, it supports complete verification of eDP source and sink devices across up to four lanes, all main link and AUX link functionality, HPD-based link training, Panel Self Refresh including PSR2 and Panel Replay, Multi-SST Operation, Display Stream Compression, Forward Error Correction, and Advanced Link Power Management.

SmartDV’s eDP VIP supports UVM, SystemVerilog, and Verilog, and integrates seamlessly into diverse verification environments. It is simulator-independent and compatible with all leading EDA simulators, providing flexibility across simulation platforms.

With comprehensive color format and video packing support, HDCP 1.3, 2.2, and 2.3 content protection, ECC and error injection, GTC-based video timing synchronization, display backlight control via DPCD registers, interlane skew insertion and deskew, dynamic scrambler control, built-in functional coverage, and a complete test suite, SmartDV’s eDP VIP enables verification teams to thoroughly validate embedded display interface designs for laptop PCs, tablets, automotive displays, and high-resolution embedded panel applications.

Key Features
  • Full Source and Sink Device Support – Provides complete eDP source and sink device functionality with support for up to four lanes, main link, AUX link, and hot plug functionality, HPD-based link training, interlane skew insertion in source mode, deskew in sink device mode, on-the-fly data generation, and all video formats supported by the DisplayPort specification.
  • Comprehensive Link Training and Scrambler Support – Supports fast, full, and skip link training via HPD, dynamic scrambler enable and disable, scrambler reset after every 512th symbol, and all DisplayPort-compatible link rates across eDP 1.3 through eDP 1.5a implementations.
  • Panel Self Refresh and Panel Replay – Supports PSR entry and exit, frame number identification in PSR, selective update for partial frame updates during Panel Self Refresh, PSR2 as per eDP v1.5, PSR Secondary Data Packet support, and Panel Replay for enhanced self-refresh with Adaptive-Sync compatibility and added power savings as introduced in eDP 1.5.
  • Multi-SST Operation (MSO) Support – Covers all defined MSO configurations including two SST links with one lane each (2×1), two SST links with two lanes each (2×2), and four SST links with one lane each (4×1), enabling verification of multi-stream embedded display topologies.
  • DSC, FEC, and Power Management – Supports Display Stream Compression as per eDP v1.5, Forward Error Correction as per eDP v1.5, Advanced Link Power Management for reduced wake latency, GTC-based video timing synchronization, display backlight control via DPCD registers, and ECC with single and multi-bit ECC error injection and detection.
  • Color Format and Content Protection – Covers RGB, YCbCr 4:4:4, YCbCr 4:2:2, YCbCr 4:2:0, Y-Only, and RAW color formats, and HDCP 1.3, 2.2, and 2.3 content protection with full authentication and bypass support for HDCP 2.2 and 2.3.
  • Comprehensive Error Detection and Reporting – Detects and reports invalid control characters, invalid data characters, invalid 10-bit codes, sync errors, scrambler errors, single and multi-bit ECC errors, and invalid packing injection and detection across all eDP protocol layers.
  • Complete Verification Infrastructure – Provides a full test suite covering all eDP specification features, built-in functional coverage analysis, constraints randomization, status counters for bus events, and callbacks in transmitter, receiver, and monitor for user-defined data processing and protocol and timing violation notification.
