Principal PCS/PMA RTL Design Engineer
San Jose, California, United States. Posted 9 days ago
The role
You will contribute to the architecture, implementation, integration, and verification of PCS/PMA digital logic for high-performance connectivity and networking ASICs. You will translate microarchitectural specifications into synthesizable RTL and collaborate with cross-functional teams to deliver designs through tapeout and silicon validation.
What you will do
- Develop synthesizable Verilog/SystemVerilog RTL for PCS and PMA digital blocks.
- Implement PCS functions like line encoding, scrambling, lane deskew, and rate adaptation.
- Implement forward error correction and related error counters.
- Implement PMA digital interface logic including SerDes datapath interfaces and control interfaces.
- Design lane-level and multi-lane logic including lane bonding and BIST features.
- Translate architectural specifications into datapaths, control logic, and state machines.
- Design reusable, configurable RTL modules.
- Integrate internal and third-party IP.
- Collaborate with design verification engineers to define requirements and test plans.
- Support logic synthesis, timing closure, and power optimization.
Required qualifications
- Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
- 3+ years of relevant experience in digital ASIC, SoC, or RTL design, or equivalent academic and industry experience.
- Hands-on experience with Verilog or SystemVerilog RTL development.
- Understanding of digital design fundamentals, including combinational and sequential logic, clocks, resets, state machines, datapaths, FIFOs, and interfaces.
- Working knowledge of at least one high-speed serial protocol (Ethernet, PCIe, UCIe, UALink, CXL, or similar) at the PCS/PHY layer.
- Experience with RTL simulation, debugging, synthesis, and basic timing analysis.
- Familiarity with ASIC design flows and collaboration across design and verification teams.
- Strong communication skills.
- Ability and willingness to work onsite in San Jose, California.
Nice to have
- Master's degree
- Direct experience designing PCS, PMA, or PHY digital logic for Ethernet, PCIe, UCIe, UALink, CXL, or similar standards.
- Experience with PAM4 signaling, FEC, lane deskew/alignment, link training, and equalization control.
- Familiarity with the PIPE specification, 802.3 series, PCIe LTSSM, and UCIe link training and sideband.
- Experience with multi-lane, multi-rate SerDes digital datapaths and clocking architectures.
- Familiarity with interconnect, networking, or data-center ASICs.
- Familiarity with synthesis and implementation tools such as Cadence Genus/Innovus or Synopsys Design Compiler/ICC2.
- Experience with STA using tools such as Synopsys PrimeTime or Cadence Tempus.
- Familiarity with lint, CDC/RDC, DFT, scan, GLS, LEC, UPF, or formal-verification flows.
- Experience with UVM, SystemVerilog Assertions, functional coverage, or verification-plan development.
