Xgig Exerciser for CXL v1.1/v2.0

The VIAVI Solutions Xgig® Exerciser for CXL™ v1.1/v2.0 brings turn-key compliance test capability to the Xgig product portfolio. An Exerciser is also a valuable tool for debugging difficult protocol communication problems because it provides full, bit-level, repeatable control over the CXL data traffic.

The VIAVI Xgig Exerciser enables in-depth protocol evaluation and debugging at 32GT/s per lane, as well as testing for CXL compliance, allowing development of memory and accelerator products to meet the demands of emerging high-speed, high-performance computing applications. With a modular architecture and an implementation tightly coupled to a full-featured analysis system, the Xgig Protocol Exerciser reduces the need for extra hardware investments, while a familiar Xgig management interface helps limit training needs, minimizing overall design and development costs.
