Full Job Description
Description

APPLE INC has the following available in Austin, Texas. Work extensively with micro-architects to define the micro-architecture, perform design feasibility and do power, performance, and area (PPA) trade-offs. Drive RTL-to-GDS design convergence through microarchitecture and logic (RTL) optimizations using synthesis and place-and-route tools targeting ambitious goals for PPA. Design block-level delivery along with closure of backend flows, electrical requirements and improving silicon yield. Work closely with internal CAD and PD methodology teams on industry standard synthesis/PNR tool features and optimizations and their adoption in CPU design. Work with cross-functional top-level teams on the aspects of CPU floorplan, timing, power, reliability, and testability. Work closely with custom IP teams to define and co-optimize memory macros, library standard cells to improve design PPA.

40 hours/week.

Minimum Qualifications

Master's degree or foreign equivalent in Electrical and Computer Engineering or related field.

Experience and/or education must include:

Designing and optimizing CPU micro-architectures by collaborating with RTL team.

Analyzing and figuring out trade-offs for CPU micro-architectural features across performance, area, timing, power, and complexity metrics, providing quantitative assessments to guide architectural decisions to achieve PPA targets within specification.

Implementing structured data-path designs using industry-standard synthesis flows, maintaining logic equivalence, performing power intent validation and timing closure through Static Timing Analysis.

Generating comprehensive timing constraints for synthesis, PnR, and STA tools supporting multi-GHz designs, ensuring high timing closure success rates and reducing design iteration cycles.

Executing floor-planning strategies including hierarchical pin placement and macro positioning for CPU designs, optimizing power grid distribution to achieve IR drop closure while meeting area utilization targets.

Applying advanced place-and-route techniques to achieve timing closure on critical paths, while meeting area density targets and optimizing dynamic and leakage power.

Developing and executing ECO methodologies to resolve timing violations, noise issues, and EMIR problems, achieving high ECO success rates and reducing design closure time.

Managing physical design verification flows to achieve zero LVS and DRC violations.

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.
