Description
The candidate will take part in the pioneering work of designing and developing innovative cross-layer simulation model infrastructure and toolsets, which will play an important role in cellular R&D across teams within Apple. The responsibilities will include but not be limited to:
Integrate PHY reference models in PHY only, reduced signaling, and full stack pre-silicon simulation and verification environments used by systems engineering, HW, FW and SW development teams.
Contribute to simulator configuration management and perform SW releases. Work on simulation framework related topics, such as regression infrastructure development, test coverage analysis, design of automation scripts as well as tool deployment and library integration.
Design and implement 4G/5G PHY models for pre-silicon simulation and verification.
Perform verification of the PHY models using 3rd Party test tools and test data provided by external network vendors.
Contribute to link-level simulator modeling, meaningful metric testing, and framework design. 4G/5G PHY/MAC layer abstraction/modeling, and interfacing with higher layers via external simulators.
Design test cases for feature verification, drive feature bring-up, and issue resolution.
Collaborate across teams to define/ document project requirements, including model architecture, interfaces, and feature sets and solve integration issues with HW and FW teams.
