LeCroy Upgrades Verification Package to Support USB-IF Link Layer Test Specification

LeCroy’ s SuperSpeed USB verification package provides a highly automated suite designed to pre-test devices for USB 3.0 conformance. The system attaches directly to host or device ports and emulates real USB 3.0 behaviors while verifying link and protocol level responses from the device under test. Fully integrated within the Voyager analyzer, the system automatically flags link layer protocol violations and saves individual trace records for later root cause analysis.

This release of the LeCroy Verification Suite includes superset coverage for the Link and Framework Test Specifications which addresses chapters 6, 7 and 9 of the USB 3.0 specification. It provides 128 separate test cases for devices and 64 test cases for USB 3.0 host ports, making it the most comprehensive test suite available for post silicon validation of USB 3.0 based devices.

Beta sites have praised LeCroy’s analyzer-based verification solution for its turn-key operation. “Integrating verification test capabilities with the LeCroy analyzer gives us one-button operation and the confidence that the results are both accurate and auditable, ” said James Ou, Allion’s Director of Personal Application Testing Center. “LeCroy’s large test suite provides the perfect compliment for our expanding verification services for SuperSpeed USB” .

Introduced in fall of 2009, the verification suite previously required Voyager systems equipped with the Exerciser option. With this announcement, LeCroy has provisioned a special configuration of the Voyager system that includes the verification suite capability without the full exerciser. The new Voyager Pro Plus analyzer allows developers to deploy more systems that incorporate automated verification during every regression cycle at a very attractive incremental cost.

“Developers working on SuperSpeed USB SOC designs or retrofitting USB 3.0 capabilities into existing products can benefit from this substantial test bed, ” said Michael Romm, Director of Product Development at LeCroy’s Protocol Solutions Group. “Using the Voyager USB verification suite to pre-test a device for USB 3.0 conformance will ultimately help developers deliver products to market earlier and with higher quality. ”
