Meet the TeamThe Common Hardware Group (CHG) creates innovative hardware platforms central to the AI era, powering Cisco's core Switching, Routing, and Wireless products for organizations globally. Our innovations in silicon, optics, and hardware platforms-like Silicon One-are shaping the technology industry. We're a global team of creative experts, bringing our unique backgrounds and bold ideas to push boundaries and help each other grow. Because full product development-from design to qualification to production-is within our team, we're able to think differently, experiment more, and work quickly. Join us to power the future of the digital world.
Join the Cisco Silicon One team in developing a unified silicon architecture for web scale and service provider networks. Cisco's silicon team provides a unique experience for ASIC engineers by combining the resources offered by a large multi-geography silicon organization and a large campus (with onsite gym, healthcare, and café, social interest groups, and philanthropy), with the startup culture and breadth of growth opportunities that working in a smaller ASIC team can provide.
You will work with exceptional talent with vast ASIC design and development expertise. With Cisco being a systems company, you will also have an opportunity to work with other ASIC teams in the journey of taking it from concept to first customer shipments.
Your ImpactYou are a diligent Design/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 develop timing constrains at both block level and full-chip and validate them using industry standard timing constraints verification tools such as TCM, Timevision. You will collaborate with Front-end 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.
- Being a member of design team who develops block level and full-chip SDCs and works with physical design and DFT teams to close full-chip timing in multiple timing modes.
- You will work design and architecture teams in understanding clocking structure, develop timing constraints and validate them though constraints verification tool before releasing them for physical design.
- Option to also do block level RTL design or block or top-level IP integration.
- Helping develop efficient methodology to promote block level SDCs to full-chip, and to push down full-chip SDCs to block level.
- Helping develop and apply methodology to ensure correctness and quality of SDCs as early as possible in design cycle.
- Reviewing block level SDCs and clocking diagrams and collaborate with RTL design owners on SDC development.
- Contribute to full-chip clocking design including diagrams and related documentation.
Minimum Qualifications- Bachelor's Degree in Electrical or Computer Engineering with 6+ years of ASIC or related experience or Master's Degree in Electrical or Computer Engineering with 3+ years of ASIC or related experience.
- Experience with synthesis tools (eg. Synopsys DC/DCG/FC), STA tools such as Primetime and must have knowledge of HDL such as Verilog/SystemVerilog programming, and scripting languages such as Shell, Perl, and must have strong experience scripting with TCL.
- Experience with digital design concepts (eg. clocking, timing exceptions and async boundaries).
- Experience with block/full chip SDC development in functional and test modes.
- Experience with microarchitecture and RTL implementation.
Preferred Qualifications - Effective documentation, problem-solving, and technical communication skills.
- Experience working cross-functionally and collaborating with various technical teams.
- You are a problem solver who loves to tackle new challenges and a self-starter who is highly motivated and thrives on innovative technology.
- You are a strong communicator in a team setting, enjoy working in a dynamic team environment, and are an out-of-the-box thinker.
