Tektronix and Anritsu have teamed up on an automated test system for the latest PCI Express 6.0 high speed links following an earlier demonstration of a test systems and work with early silicon designs from Synopsys.

The PCIe 6.0 Receiver Test Solution equips engineers to test PCIe 6.0 (Base) receivers for high speed interconnect in AI and data centre applications. Tektronix provides a cohesive PCIe 6.0 transmitter and receiver test with the Tektronix DPO70000SX Real-Time Oscilloscope, combined with Anritsu’s MP1900A signal quality analyser.

Tektronix and Anritsu started collaborating early for PCIe 6.0, working with Synopsys on early validation of their PCIe 6.0 DesignWare IP. This provided early-stage prototypes for the partnership with Anritsu.

“A combined solution delivers an innovative improvement to the market and a complete physical layer PCIe test system that can be expanded to PCIe 6.0 as the market continues to develop technologies for high-speed networks,” said Kazuhiro Fujinuma, Director of Solution Marketing Department Service Infrastructure Division for Anritsu.

“The PCIe 6.0 interface is instrumental to enabling real-time data connectivity with low latency and high throughput in HPC, storage, and AI applications,” said John Koeter, senior vice president of marketing and strategy for IP at Synopsys. “Conducting early, accurate and efficient validation of the Synopsys silicon-proven PCIe 6.0 IP with Tektronix solutions demonstrates that the IP adheres to the latest PCI-SIG specifications, enabling designers to deliver interoperable products that include Synopsys PCIe 6.0 controller, PHY, verification, and Integrity and Data Encryption (IDE) IP faster and with less risk.”

PCIe receiver validation is notoriously difficult due to the sensitivity of calibrating the stressed eye signal across a high loss channel. Tektronix’s PCIe receiver test solutions provide confidence that designs are thoroughly tested at the required bit error rate (BER) target. The intuitive step-by-step tools provide link training routines for the Anritsu MP1900A BERT to ensure the receiver is tested accurately.

The Tektronix PCIe 6.0 Base Rx Solution includes the fastest 64 GT/s (PAM4) Rx calibration in the industry. Novel algorithms efficiently address the new challenge of calibrating the Transmitter’s additional pre-cursor added to the 6.0 Base specification.

The Tektronix PAMJET DSP tool provides critical 64 GT/s jitter and noise measurements with advanced instrument noise compensation. This fully automated solution leverages the first-to-market 6.0 Base Tx solution techniques and enhances the capabilities to address Receiver challenges at the latest data rate introduced by the PCI Special Interest Group (PCI-SIG®).

The TekRxTest automation software provides a single control panel with the power to manage a Tektronix oscilloscope and Anritsu BERT during receiver calibration. The software wizard guides users through short- and long-channel calibration steps, resulting in an accurate and repeatable calibration at 64 GT/s.

The PCIe 6.0 (64 GT/s) automated test solution runs on the Tektronix DPO70000SX series real-time oscilloscope and the Anritsu MP1900A BERT  with the first fully automated PCIe 6.0 Rx stressed eye calibration with the Anritsu MP1900A BERT. Full short- and long-channel 64 GT/s Rx calibration cab ve completed in four hours or less with high-fidelity measurements using the Tektronix PAMJET DSP engine.

Tektronix’s PCIe 6.0 Receiver Test Solution is available worldwide for use with DPO70000SX Real-Time Oscilloscopes.
