Verification IP for LPDDR4

Synopsys® Verification IP for the JEDEC LPDDR4 memory protocol specification provides a comprehensive set of protocol, methodology, verification and productivity features, enabling users to achieve rapid verification convergence on LPDDR4 based designs. VIP can be integrated, configured and customized with minimal effort. Testbench development is accelerated with the assistance of built-in verification plans, example tests, and functional coverage. VIP is natively integrated with Verdi® Protocol Analyzer, a protocol-centric debug environment that gives users graphical view of VIP operations, transactions, and memory content view for easy and fast debug.  VIP is natively integrated to Verdi Performance Analyzer also to find and fix performance bottle necks.

Memory Model Certification

Synopsys provides a comprehensive set of DRAM and Flash Memory VIP that support the latest ratified and draft specifications from standards organizations such as JEDEC, ONFi, SD, and SPI. Synopsys’ VIP team works closely with leading memory vendors to certify 100% compatibility with their manufactured parts. Synopsys Memory VIP is used by memory controller and PHY IP design teams for verification sign off using run time and random JEDEC, and vendor part selection, protocol, and timing checks, and functional coverage. The early adoption and collaboration with leading memory vendors, SoC market makers, and industry leading IP teams certify the quality of Synopsys Memory VIP.
