Job description

Mixed-Signal Behavioral Modeling Engineer

At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for an ambitious and extraordinarily hardworking Mixed-Signal Behavioral Modeling Engineer. As a member of our dynamic group, you will have the unique and rewarding opportunity to craft upcoming products that will delight and support millions of Apple’s customers every single day. In this role, you will work within the mixed-signal design team to model complex custom circuits for the purpose of verifying system-level functionality and performance. This is a rewarding cross-disciplinary position, with a high degree of collaboration across multiple teams. This role will provide the opportunity to work on state of the art mixed-signal systems used in Apple’s world-leading SoCs, and shape the cutting edge of the behavioral model field.

Description

In this role, you will be responsible for writing functional models of custom mixed-signal circuits in SystemVerilog with the right amount of detail, while also incorporating non-idealities. You will collaborate with circuit design teams to understand details of custom circuits, and with DV teams to craft hooks into the models for effective verification. You will analyze data provided by the circuit team in Python/MATLAB for fitting into the model and analyze the performance of the resulting model by profiling. You will run simulations and formal equivalence tools to ensure that the model matches closely with the custom circuits. You will work with other experts in this domain to enhance modeling methodology, improve functional coverage, optimize modeling flows and enable new tools to identify custom circuit issues.

Minimum Qualifications

• BS degree in technical discipline with minimum 10 years of relevant experience.

Preferred Qualifications

• Excellent knowledge of digital logic gates, clocking and state elements
• Excellent knowledge of writing behavioral code in SystemVerilog
• Solid understanding of logic and behavioral simulations
• Ability to read custom circuit schematics and understand functionality
• Good familiarity with circuit elements and functionality of mixed-signal blocks such as PLLs/DLLs/SERDES/Sensors/Data-converters
• Good understanding of SPICE circuit simulations, and SystemVerilog/SPICE co-simulations
• Good understanding of timing synchronous digital logic
• Ability to write scripts in PERL/Python to automate repetitive tasks
• Familiarity with the basics of digital signal processing and numerical analysis
• Familiarity with the basics of probability and statistics
