SOC Clocks RTL Design Engineer
Nvidia · Tel Aviv
The complexity of the chip has greatly increased over the years. We are now packing tens of billions of transistors in a chip to meet the growing computing demand in a footprint that is responsible to our environment. The NVIDIA System-On-Chip (SOC) group is looking for a strong RTL Design Engineer to own the SOC clocking logic for our next-generation networking chips. Clocks are the backbone of the SOC. In this role you will own the clock generation, distribution, and control logic for the entire chip — PLL and reference clock integration, clock muxing and dividers, glitchless switching, clock gating, reset synchronization, and the clock domain crossing infrastructure that every unit on the die depends on.
This is an RTL design role, not a circuit or transistor-level design role. You will translate micro-architecture specifications into high-quality synthesizable RTL, and drive that RTL through to silicon in close partnership with the micro-architecture, Design Verification, and Physical Design (backend) teams. You will also interact with CAD, Package Design, Software, and DFT teams.
What you'll be doing:
Owning the SOC clocking logic end to end: writing synthesizable Verilog/SystemVerilog RTL for clock generation, distribution, muxing, division, glitchless switching, gating, and reset synchronization, from micro-architecture specification through tape-out
Defining and implementing the SOC clock and reset architecture together with the micro-architecture team — collecting clocking requirements from every unit on the chip and turning them into a coherent, verifiable design
Owning clock domain crossing infrastructure and CDC closure across the SOC
Partnering with the micro-architecture team to review specifications, close on design intent, and provide feedback on implementation cost, timing, area, and power
Working hand-in-hand with the Physical Design (backend) team on clock tree implementation and constraints, partitioning, floorplan and timing feedback, trial synthesis, congestion and timing convergence, and physical design readiness
Supporting Software and firmware teams on clock programming sequences, DVFS, and low-power/clock-shutdown flows
Driving design quality: lint, CDC/RDC, formal checks, synthesis QoR, connectivity and structural checks
Supporting SOC-level chip build and assembly, and developing/deploying automation flows that make RTL integration and design quality checking repeatable and scalable
Supporting emulation, firmware, and post-silicon bring-up customers of your design
What we need to see:
B.Sc./M.Sc. in Electrical Engineering or Computer Engineering
3+ years of relevant experience in RTL/logic design
Solid hands-on RTL design skills in Verilog/SystemVerilog, with a good understanding of synthesis, timing, and how RTL choices affect the physical implementation
Experience taking a design from micro-architecture specification through verification and physical implementation
Solid understanding of clocking and reset concepts: clock gating, clock muxing and dividers, glitchless clock switching, reset synchronization, and clock domain crossing
Familiarity with design quality tooling (lint, CDC/RDC, formal, synthesis)
Great teammate with strong communication skills across micro-architecture, DV, and backend teams
Ways to stand out from the crowd:
Passion for quality, and a track record of clean deliveries to physical design, DV, emulation, firmware, and other downstream customers
Prior ownership of SOC-level clocking or reset architecture on a taped-out chip
Experience with PLL/clock generator integration and clock tree constraint development with backend teams
