Post Silicon Validation

• *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.
