Avery Design Systems Announces UFS Host Controller UFSHCI Verification Solution

ANDOVER, MA. - October 8, 2013 – Avery Design Systems Inc., a leader in verification IP, today announced availability of its UFS Host Controller Interface (JESD223 UFSHCI) verification solution supporting the latest embedded mobile storage solutions comprised of MIPI UniPro and M-PHY, and JEDEC UFS specifications.

The new release of MIPI-Xactor allows design and verification engineers to quickly and extensively test the functionality of both UFSHCI-compliant host controllers and UFS devices.

Avery provides a complete verification solution consisting of SystemVerilog UVM/OVM/VMM compliant models and environment, protocol checkers, directed and random compliance test suites, and reference verification frameworks.  Additional advanced debug features include multi-level analyzer trackers to visualize data and control flow through the protocol stacks.
