PCI Express Protocol Analyzer

  • The Hierarchical Protocol Tree View organizes the captured PCI Express protocol data into a format that exactly reflects the nesting of the actual protocol items on the bus. This greatly eases understanding of the PCI Express protocol. Other PCI Express Protocol Analyzers use a primitive block-type display which makes it very hard to see the overall hierarchy of the complex data being communicated.
  • FPGA hardware acceleration (indexing) of protocol items allows instantaneous Protocol View display after custom filtering, even for a full 2 gigabyte capture. Other Protocol Analyzers use the computer's CPU to parse the captured data which is orders of magnitude slower.
  • Idle Data Hardware Filtering allows capture of minutes worth of link data, allowing tens of millions of protocol items to be captured. This will allow you to capture rare or unknown events that are otherwise impossible to set up trigger conditions for.
  • Dynamic on-demand data upload from the hardware allows effortless access to and browsing of gigabyte sized trace data without a need to first upload the complete data to the PC. Only the part of the Protocol View that is actually visible will result in data fragments being uploaded from the 2500A unit.
  • Extremely deep Trigger Sequence Detectors allow detection of eight trigger levels of up to 2,048 bytes per level or in total 16 kilobytes. Other Protocol Analyzers normally only allow you to trigger on a few DWords of packet payload data.
  • Multiple time-correlated views of the data are simultaneously available, allowing you to easily see transaction, packet and lane details from the highest to lowest abstraction levels at a glance. Some other PCI Express Protocol Analyzers require you to change the protocol view to view the data at a different abstraction level, resulting in lengthy reparsing of the data as well as loss of situational awareness of your location within the overall trace.
  • Hardware acceleration of Protocol Item detection allows immediate display of the number of each type of protocol item in the trace as well as immediate jump to or filtering of any protocol item type.
