Verification IP for DFI
草榴社区 Verification IP (VIP) for DFI provides a comprehensive set of protocol, methodology, verification, and productivity features, enabling users to achieve accelerated verification closure of DFI based designs.
VIP, based on its next generation architecture and implemented in native System Verilog/UVM, runs natively on all major simulators. VIP can be integrated, configured and customized with minimal effort. Test bench development is accelerated with built-in verification plan and functional coverage.
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.
