Job Description

Job Requirements

Post-Silicon Validation Architect (Display Team)

Role Overview

The Post-Silicon Validation Architect defines the validation strategy, test plans, and automation frameworks to bring up and qualify next-generation display chips. This role bridges hardware design, FPGA prototyping, and production software to ensure the silicon meets all functional, performance, and reliability targets before mass production.

Key Responsibilities

  • Architecture & Strategy: Define the post-silicon validation architecture, methodologies, and test strategies for display chipsets.
  • Bring-up & Debug: Lead the bring-up of silicon, reference boards, and FPGA prototypes, isolating complex hardware and software defects.
  • Test Development: Create comprehensive test plans covering display protocols, frame buffer management, pixel pipelines, and image processing algorithms.
  • Automation: Design and scale automated test frameworks to interface with high-speed validation equipment.
  • Cross-functional Collaboration: Partner with Design, Pre-Silicon Verification (SV/UVM), Emulation, and Firmware teams to root-cause chip bugs.

Required Technical Skills

Display, Video, & Pixel Processing

  • DSI2 & MIPI: Deep knowledge of MIPI DSI-2 physical and protocol layers for high-speed mobile and automotive displays.
  • Pixel Formats & Formats: Mastery of raw pixel data formats, including PACKED YUV444 and RGB data streams.
  • Bit Depth & Color: Expertise in validating variable bit depths (e.g., 8-bit, 10-bit, 12-bit per channel) and their impact on color fidelity. [1]
  • Scaling & Processing: Strong understanding of image processing pipelines, specifically upscale and downscale filtering engines.
  • Display Technologies: Deep knowledge of display panels, display drivers, demura (mura correction) algorithms, and color management systems.

Hardware Validation & Equipment

  • Introspect Technology: Hands-on experience using Introspect SV series systems (or similar MIPI protocol analyzers/exercisers) for protocol conformance and physical layer testing.
  • FPGA Prototyping & Emulation: Experience using FPGA platforms (Xilinx/AMD, Intel, or Zebu environments) for pre-silicon development and early post-silicon software alignment.
  • Lab Instrumentation: Mastery of high-speed oscilloscopes, multimeters, logic analyzers, and bit error rate testers (BERT).

Silicon Characterization & Verification Methodologies

  • Bitstream Verification: Experience developing and executing bitstream verification methodologies to validate code compliance and pipeline robustness.
  • SV/UVM Understanding: Strong understanding of SystemVerilog and UVM (Universal Verification Methodology) to effectively bridge pre-silicon testbenches with post-silicon test plans.
  • PVT Testing: Experience characterizing silicon performance across Process, Voltage, and Temperature corners.
  • Frame Buffer: Expertise in validating memory interfaces, frame buffer bandwidth, display refresh rates, and power-saving modes.
  • Functionality: Full-stack functional validation of chip configuration, register maps, interrupts, and power management states.

Software, OS, & Automation

  • Python Programming: Advanced Python programming skills for building, scaling, and maintaining automated test scripts, with tools and frameworks.
  • Low-Level Software: Experience writing and debugging firmware in baremetal environments and RTOS platforms.
  • OS Ecosystems: Familiarity with display subsystem pipelines within host operating systems, specifically Android (SurfaceFlinger/HWC) and Linux (DRM/KMS drivers).
  • Excellent problem-solving abilities and attention to details
  • Good software debugging skills using tools like gdb, Valgrind etc.
  • Experience in Continuous Integration tools like SVN, Git, Jira etc.

Soft Skills

  • Strong communication skills for clearly communicating ideas and concepts to team/customer

Qualifications

  • Education: Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.
  • Experience: 8+ years of experience in post-silicon validation, specifically within display, multimedia, or high-speed SoC environments.
