SerialTek delivers full visibility into PCI Express® networks
BusXpert iTAP Framework features Broadcom Gen5 PEX89000 PCI Express® embedded analyzer technology, delivering deeper analysis and diagnostic capabilities on-chip.

Advancing the the PCI Express (PCIe®) test and analysis market, SerialTek has released BusXpert™ iTAP™, a convenient "tap" framework integrated with BusXpert analyzer software for the Kodiak™ PCIe Gen5 x16 Protocol Analysis System, providing PCIe developers the ability to set up, capture, decode, and view PCIe trace data captured on-chip by Broadcom's PCIe Embedded Analyzer technology.

The iTAP framework supports PCIe Embedded Analyzer technology, a groundbreaking offering in Broadcom's new PEX89000 Gen5 PCIe switch platform. When used in conjunction with the Kodiak protocol analysis system, PCI Express developers can seamlessly transition between Kodiak's deep PCIe traces and iTAP embedded traces.

With Kodiak PCIe Analyzers and BusXpert Protocol Analysis software from SerialTek, users can analyze and debug PCIe traffic with a rich feature set and high flexibility that customers and the industry have come to expect. However, with today's highly integrated systems where switches and many chip-to-chip interconnects exist, physical limitations to accessing all possible PCIe interconnects at their point of origin can prove challenging. BusXpert iTAP solves this problem by harnessing and directly connecting to each instance of Broadcom's PCIe Embedded Analyzer technology with no additional hardware required.

"Broadcom had the foresight to know they needed a collaboration with a protocol analyzer company to make this embedded analyzer as effective and impactful as it could be," says Paul J. Mutschler, CEO of SerialTek, "With our history in protocol analysis and new advancements in modern WebUI interfaces, we were an obvious choice for this new Broadcom tool." Broadcom integrated this technology into its PCIe Gen5 PEX89000 switches and supports the following robust feature set:

  • BusXpert iTAP - Integrated with BusXpert for common PCIe trace analyzer software.
  • Embedded Analyzer - No external hardware required, eliminating probe insertion challenges.
  • Advanced Trigger Capabilities, Programmable filtering, Data compression - Fully capable embedded solution.
  • Parallel Analysis - Embedded analyzers capable of triggering other instances to allow for synchronized parallel analysis.
  • In-band (PCIe) and out-of-band connectivity (JTAG).

The Kodiak platform introduces major performance-oriented innovations made possible by an embedded architecture that breaks free from legacy data upload practices in favor of advanced, optimized embedded data processing, fully reimagined by SerialTek engineering from the ground up to handle latest- and future-generation PCIe technologies. Interface responsiveness is markedly advanced, searches involving massive amounts of data are fast, and hardware filtering is flexible and powerful.
