COSMOS Tools

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.”
