Verification IP for LPDDR3
草榴社区 Verification IP (VIP) for the JEDEC LPDDR3 memory protocol specification provides a comprehensive set of protocol, methodology, verification and productivity features, enabling users to achieve accelerated verification convergence on LPDDR3 based designs. VIP LPDDR3 is integrated, configured and customized with minimal effort. Testbench development is accelerated with 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.
Memory Model Certification
草榴社区 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. 草榴社区’ VIP team works closely with leading memory vendors to certify 100% compatibility with their manufactured parts. 草榴社区 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 草榴社区 Memory VIP.
