Full Description
Job Description
Develop and execute validation plans for HSI systems, such as PCIe, USB, DP, HDMI, UFS, CSI, and UCIe PHY. Design, implement, and maintain test benches and validation environments for system-level and interface-level testing. Perform signal integrity and protocol compliance testing using industry-standard tools and equipment (e.g., oscilloscopes, logic analyzers, protocol analyzers). Analyze test results, identify root causes of failures, and work closely with design and firmware teams to resolve issues. Document validation procedures, test results, and provide detailed reports to stakeholders. Collaborate with cross-functional teams including hardware, firmware, and software engineers to ensure seamless integration and validation of HSI systems. Design and develop hardware PCB evaluation boards for HSI system validation. Conduct schematic capture, component selection, and PCB system design for evaluation boards. Support board bring-up, debugging, and troubleshooting of hardware evaluation platforms. Stay updated with the latest industry standards and best practices for HSI and PCB system design.
