Cspeed IO is a stealth start up backed by Sutter Hill Ventures and Atreides Capital - headquartered in Palo Alto, CA. Our executive team has a demonstrated track record of building and scaling category-defining semiconductor and infrastructure businesses at companies like Broadcom, Lumentum, Tesla, Apple, Samsung, Intel, and VMware.

Cspeed IO is developing next-generation optical semiconductor solutions for the AI infrastructure market, focused on enabling true “scale-up” architectures. Our mission is to replace traditional copper interconnects with advanced fiber-optic technologies that overcome the limitations of existing optics solutions and architectures.

Role Summary The Emulation Lead is responsible for driving pre-silicon validation and performance analysis of complex Data Center SoCs using hardware emulation platforms. This role ensures early software bring-up, system-level validation, and debug of critical features before tape-out. The position involves architecting emulation strategies, building scalable environments, integrating IPs and subsystems, and enabling workloads representative of real data center use cases.

Key Responsibilities

- Define emulation methodology for data center SoCs with CPU, NOC/Crossbar, Ethernet and high-speed IOs.
- Develop partitioning strategies& set up emulation environments (Palladium, Veloce, ZeBu)



and partition RTL for hardware-based platforms.
- Port large-scale SoCs/IPs onto emulators, bring up the platform, and debug interface/functional issues involving firmware/hardware.
- Integrate and develop synthesizable monitors/checkers, VIP transactors,NOC bridges (MAC/PHY DDR)
- Emulation prototyping forboot loader bring-up, SoC configuration, first power-on sequences, clock/reset validation, strap/fuse programming
- Own stress testing and completeness of data path includingEthernet PHY/MAC link bring-up, loopback tests; validate DMA descriptors, interrupts
- Automate emulation regression flows using scripting (TCL, Python, Perl) andoptimize for coverage and debug time.
- Collaborate closely with verification, firmware, software, architecture teams for pre-silicon validation and bring-up.

Required Skills

- Solid exposure of emulation platformCadence Palladium, Synopsys ZeBu, Mentor Veloce
- Strongproficiency in C/C++ and RTL partitioning for emulation platforms.
- Drive validation activitiesex: bootloader bring-up and executing real-world workloads.
- Waveform analysis, transaction-level debug, log parsing
- Emulation + virtual models, FPGA prototyping.

Added Advantage

- Understanding of System Verilog/UVM, SVA, coverage-driven verification
- Python/TCL scripting experience and post-silicon bring-up
