Full Job Description
In this job, you will be responsible for timing closure of highly complex GPU designs that go in every Apple product and will have amazing opportunities to set new standards for the next generation GPU designs. You will gain exposure to different aspects of product development, from concept to post silicon validation! You will collaborate with a variety of fields including Architecture, RTL, Synthesis, Clocking, DFT, Physical design and Post silicon engineering to ensure the best design practices are followed for a smooth timing convergence.

Description

In this role you will:

- Lead different STA activities at the same time by working with functional collaborators.

- Identify dependencies and roadblocks for different STA items very early on and ensure a smooth execution of timing closure.

- Participate in analysis leading to the definition of next generation products.

- Interact with RTL, architecture teams to understand physical design constraints related to timing and be the central point of contact to provide these to backend design flows.

- Work with Synthesis and Physical Design teams to implement the best design optimized for power, performance and timing.

- Setting up all DFT modes and making sure all test features are properly timed.

- Assemble the top level design for STA ensuring accurate analysis by reviewing all the logs and reports.

- Create and maintain scripts and automation to ensure high quality STA reports and work with other teams for timing closure.

- Run ECO flows on the design and responsible for close timing.

- Drive and support tapeout activities by running a full suite of signoff checks to ensure a high quality silicon for manufacture.

- Work with CAD and Vendors to constantly improve the flow and bring in groundbreaking features to the analysis flows.

- Work with post silicon teams and product engineering for silicon debug activities.
