Timing Constraint Engineer

Meet the Team

The Common Hardware Group (CHG) delivers the silicon, optics, and hardware platforms for Cisco's core Switching, Routing, and Wireless products. CHG silicon chips, optical modules, and full hardware systems solve for a range of demanding use cases from access points for a medium size business, to an enterprise data center, and the largest of hyperscale AI workloads. We are team passionate about technology, have aspirational goals, and love to win as a team.

Your Impact

You are a detail-oriented Timing Constraint (SDC) Engineer with strong analytical skills and a deep understanding of timing constraints, including clock groups, exceptions, and clock exclusivity. Proficient in industry-standard SDC/STA tools and scripting for automation, you excel at identifying and resolving timing issues across all design levels. You will collaborate with ASIC Front and Back-end teams to understand chip architecture and guide them in refining design and timing constraints for seamless physical design closure. As part of this team, you'll contribute to developing next-generation networking chips. Responsibilities include:

• Developing timing constraints at block, sub-chip, and full-chip levels in multiple timing modes.
• Performing quality checks such as duplicated constraints, promotion/demotion between block and top level SDCs and checking timing for unconstrained endpoints, no clock, etc.
• Resolving design and flow issues and driving execution to ensure progress and accuracy.
• At times participating in SDC validation, CDC delay check, and SDC flow development.
• Developing methodologies, guidelines, and checklists to streamline STA work, along with advising the Physical Design team on best practices.
  

Minimum Qualifications

• Bachelor's degree in electrical or computer engineering (or other equivalent field) with 8+ years of related work experience.
• Experience with block/full chip SDC development in functional and test modes.
• Experience in Static Timing Analysis and prior working experience with STA tools like PrimeTime/Tempus.
• Proficient in one or more of the following languages Perl, TCL, Python, Makefile, or other related scripting languages.

Preferred Qualifications

• Master's Degree in electrical or computer engineering (or other equivalent field).
• Thorough understanding of Liberty file formats including standard cells/memory/IO/IP modeling and its usage in the ASIC flow.
• Prior experience with SDC debugging tools: Synopsys GCA/TCM, Cadence CCD.
• Strong communications skill and team player.

Why Cisco?

#WeAreCisco. We are all unique, but collectively we bring our talents to work as a team, to develop innovative technology and power a more inclusive, digital future for everyone. How do we do it? Well, for starters - with people like you!

Nearly every internet connection around the world touches Cisco. We're the Internet's optimists. Our technology makes sure the data travelling at light speed across connections does so securely, yet it's not what we make but what we make happen which marks us out. We're helping those who work in the health service to connect with patients and each other; schools, colleges and universities to teach in even the most challenging of times. We're helping businesses of all shapes and size to connect with their employees and customers in new ways, providing people with access to the digital skills they need and connecting the most remote parts of the world - whether through 5G, or otherwise.

We tackle whatever challenges come our way. We have each other's backs, we recognize our accomplishments, and we grow together. We celebrate and support one another - from big and small things in life to big career moments. And giving back is in our DNA (we get 10 days off each year to do just that).

We know that powering an inclusive future starts with us. Because without diversity and a dedication to equality, there is no moving forward. Our 30 Inclusive Communities, that bring people together around commonalities or passions, are leading the way. Together we're committed to learning, listening, caring for our communities, whilst supporting the most vulnerable with a collective effort to make this world a better place either with technology, or through our actions.

So, you have colorful hair? Don't care. Tattoos? Show off your ink. Like polka dots? That's cool. Pop culture geek? Many of us are. Passion for technology and world changing? Be you, with us! #WeAreCisco
