COSMOS CLI and COSMOS Explorer for link management, monitoring, and debugging

Request the Evaluation Kit

Accelerate silicon design, bring-up, and validation

  • Gain visibility across physical, data link, and protocol layers – from signal integrity and margining to LTSSM states and error metrics
  • Reduce manual debug cycles with real-time visibility into link training, speed changes, recoveries, protocol logs and more
  • Execute repeatable validation workflows, including stress testing, protocol checks, and telemetry capture
  • Modify link parameters, trigger tests, and capture rich diagnostics from a unified control plane

Testimonials

“With COSMOS CLI, we can quickly read the PCIe link status and capture the firmware logs directly from the device. This eliminates the need for additional tools to capture firmware logs and greatly improves work efficiency.”

“COSMOS CLI just worked. Sharing the same tools as the Astera Labs engineering team removed debug friction and significantly accelerated platform bring-up.”

“SK hynix leveraged the advanced visual capabilities of the COSMOS Explorer tool to swiftly comprehend and pinpoint the root cause of incompatibility occurrences, streamlining the PCIe 6 eSSD bring-up process.”

Lighting the Way: Demonstrated Progress on Our Optical Roadmap to NPO and CPO

Earlier this year, Astera Labs outlined how we’re responding to the demand for low-power, ultra-low-latency, high-density, high-speed links as AI outgrows the rack. We demonstrated our progress toward this goal with a high-radix linear pluggable optics (LPO) demonstration at Computex 2026.Our flagship event of the year, the OCP Global Summit, has now wrapped up, and it’s the right… Read more

One High-Radix Switch, 89% More Tokens/s: Scorpio X-Series Outperforms Conventional Switches in 8-GPU Clusters

AI infrastructure has entered the era of the “AI factory.” Inference workloads dominate AI compute and hyperscalers are increasingly focused on profitable tokens/s generation. Inference accounts for roughly two-thirds of all AI compute in 2026, up from about a third in 2023, and the trend line only points up.1The AI fabric has a real impact on tokens per second, and the switch that connects… Read more
