INSPECTOR for PCIe
INSPECTOR for PCIe
Interposer Card for Diagnostic Testing, Exercising and Debug of PCIe Devices at up to Gen4 16GT/s speed
INSPECTOR is a PCIe 4.0 compliant interposer module designed for non-intrusive monitoring, diagnostic, exercising and debug of PCIe devices. INSPECTOR uses transparent switching technology to connect on the upstream side to a PCIe host platform, and on the downstream side to the device under test (DUT). INSPECTOR supports PCIe 1.x, 2.x, 3.x, and 4.0 interfaces on either ports, and up to 8 lanes (x8). It is typically used for bring-up and diagnostic testing of PCIe 4.0 DUTs at PCIe 4.0 16GT/s speed using existing PCIe hosts operating at PCIe 3.0 8GT/s speed, but can support any link speed/width combination on upstream and downstream ports. INSPECTOR's built-in diagnostic capabilities allows validation engineers to instantly diagnose issues with their PCIe devices, without the need for expensive test equipment. In particular, it enables design, test and validation engineers to:
- Monitor PCIe interface power-on process
- Diagnose PCIe interface PHY and link issues
- Analyze throughput performance in real-time, in production environment
- Check PCIe interface reliability
- Perform PCIe interface stress tests and random tests via scripting (exerciser functionality)
It also allows firmware/software engineers to develop their devices firmware and software on the actual production system running the Operating System of choice.
INSPECTOR is used as a PCIe 4.0 Host Interoperability platform at PCI-SIG Compliance Workshops (PCIe 4.0 testing).
