Cross-layer analysis

Interoperability issues can lead to finger-pointing exercises that cost money and time-to-market. Teledyne LeCroy CrossSync PHY software and interposers seamlessly merge the functions of your Teledyne LeCroy protocol analyzer and oscilloscope – giving insight into link behavior that no other instrument can provide.

The CrossSync PHY concept

CrossSync PHY enables waveforms from Teledyne LeCroy oscilloscopes to be viewed alongside protocol analyzer traces, with complete time-correlation of electrical and protocol information for easy and powerful validation and root-cause analysis.

A growing range of CrossSync PHY capable interposers eliminates the complexity of cross-probing the same interface for capture by both the protocol analyzer and oscilloscope.

The CrossSync PHY concept

Validate and debug active link operation

  • CrossSync PHY capable interposers enable observation of both electrical and protocol behavior without disturbing the link
  • Sideband signals, reference clock and power rails are all easily accessible to oscilloscope probes
  • Optional high-bandwidth oscilloscope probing points for PCI Express data lanes

Quickly resolve interoperability issues by capturing the entire protocol stack

  • Trigger protocol analyzer and oscilloscope captures on the same high-level event
  • Easily measure timing relationships between protocol and electrical domains
  • Faster root-cause analysis means fewer costly finger-pointing exercises

Analyze link training with integrated physical and protocol views

  • Observe electrical-level results of protocol-level commands
  • Combined navigation means always knowing which protocol and electrical behaviors happen at the same time
  • No single instrument can deliver this level of cross-layer insight into link training

More visibility

CrossSync PHY gives deeper insight and more visibility into the most complex behaviors in a PCI Express link. Link training, power-on operations, and power management transitions all involve interactions between protocol and electrical layers.

Dynamic Link Behavior

  • Characterize entire boot sequence with visibility into sideband signals, reference clock, data lanes and power rails.
  • Observe speed changes in both electrical and protocol domains.
  • Trigger on problematic link training behaviors and analyze their consequences through the entire protocol stack.

CrossSync PHY cross-analysis software

The CrossSync PHY software option for your Teledyne LeCroy oscilloscope enables precise, intuitive navigation between time-correlated protocol analyzer and oscillscope traces.

  • 1CrossSync PHY navigation bar makes clear the timing relationship between linked protocol analyzer and oscilloscope captures.
  • 2One or many oscilloscope acquisition segments are represented in the navigation bar.
  • 3Protocol analyzer trace represented in the navigation bar.
  • 4Common trigger point ensures precise timing alignment between protocol trace, oscilloscope acquisitions, and navigation bar view.
  • 5Oscilloscope timebase and protocol analyzer acquisition window remain synchronized while navigating through the combined acquisition, for total confidence in timing behavior.
  • 6Selecting a packet on the protocol trace enables zoom traces on the oscilloscope to the same time window, enabling sub-packet-level measurement precision
