Full Job Description
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

About Apple

Apple is a corporation that designs, manufactures, and markets mobile communication and media devices, personal computers, portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. Apple provides many products and services, including iPhone; iPad; iPod; Mac; Apple TV; a portfolio of consumer and professional software applications; the iOS and OS X operating systems; iCloud; and accessories, service, and support offerings. It sells its products worldwide through its retail stores, online stores, direct sales force and third-party cellular network carriers, wholesalers, retailers, and value-added resellers to the consumer and also sells third-party iPhone, iPad, Mac and iPod compatible products, including application software and accessories through its online and retail stores. Introduced in 1984, the Macintosh was the first widely sold personal computer with a graphical user interface (GUI). That feature and others such as an improved floppy drive design and a low-cost hard drive that made data retrieval faster helped Apple cultivate a reputation for innovation. Apple was named as the most admired company in the United States in 2008 and in the world from 2008 to 2012 by the Fortune magazine. The company was founded by Steven Paul Jobs, Steve Wozniak, and Ronald Gerald Wayne on April 1, 1976, and is headquartered in Cupertino, California.
