Core / CPU validation
Architectural and microarchitectural compliance, ISA conformance, IPC characterization, errata isolation, and corner-case stress under all P-state and C-state transitions.
Pre- and post-silicon validation across core, memory, I/O, power, thermal, performance, and electrical domains. Built to the standards Qualcomm, Broadcom, Intel, AMD, and Nvidia run on their own platforms before shipping.
Modern silicon is fragile in subtle ways. A processor that simulates clean can still fail intermittently in the field at high temperature, under voltage droop, on a specific I/O pattern, or when DDR refresh aligns with a particular workload. Catching those failures is a discipline.
Platform validation is what happens between chips that work and chips that ship. It is rigorous, expensive, and unglamorous — and the leading semiconductor and platform companies pour enormous resources into it precisely because the field cost of an undetected bug is catastrophic.
We bring the methodology and the muscle: test infrastructure, automation, characterization, debug, and root-cause across the full validation matrix that platform vendors care about.
Architectural and microarchitectural compliance, ISA conformance, IPC characterization, errata isolation, and corner-case stress under all P-state and C-state transitions.
DDR4 / DDR5 / LPDDR5 / HBM3 training, margining, refresh-corner stress, ECC injection, NUMA latency, and bandwidth envelope characterization across temperature.
PCIe Gen4 / Gen5 / Gen6, CXL 1.1 / 2.0 / 3.0, USB4 / Thunderbolt, Ethernet 100/200/400G, SATA, and proprietary high-speed serial. Eye margining, jitter, equalization.
Voltage rail margining, droop characterization, dynamic and static power across workloads, sleep-state entry/exit, and power-management firmware compliance.
Junction-temperature characterization, thermal-throttling correctness, hotspot mapping with IR / thermocouple instrumentation, and TDP envelope verification.
Industry benchmark suites (SPEC CPU / SPEC Power, MLPerf, STREAM, etc.) plus customer workload replay. Performance regression and uplift attribution.
Pre-silicon SI/PI simulation, post-silicon validation against compliance masks, oscilloscope and BERT measurement, and S-parameter de-embedding.
Test framework engineering, lab equipment automation, distributed test orchestration, results database, and statistical regression analysis at fleet scale.
A practical, opinionated stack — chosen for production reliability, not novelty. We add to it carefully, and we share what we learn.

We work with a small number of partners each year. The right first step is usually a conversation. Or look at what we build.
