This tutorial presents a more complex design example, and it demonstrates the process of refining the design to achieve performance goals. You will start with a system DDR traffic spec and learn how to model this with the NoC, DDR memory controllers, and AXI traffic generators (TGs).
Build a UVM Environment for an parametrized memory module, including uvm testbench architecture components such as; sequencer, driver, monitor, scoreboard and subscriber. design was verified using QuestaSim. - tonyalfred/Memory-Verification-using-UVM.
DDR4 SDRAMs are very prevalent in devices that use ASICs and FPGAs. In this tutorial we explore the basics of DDR4 memory starting with what it looks on the inside, how basic operations such as READ and WRITE work, DRAM page size, ranks and addressing.
10 Ιουν 2024 · DDR-RAM stands for Double Data Rate Synchronous Dynamic Random-Access Memory. These are the computer memory that transfers the data twice as fast as regular chips like SDRAM chips because DDR memory can send and receive signals twice per clock cycle as a comparison.
3 Φεβ 2023 · Learn about double date rate (DDR) memory key concepts and applications surrounding this digital communication technique, where two data words are transferred during one clock cycle.
1 Φεβ 2021 · In this article, Nishant looks at DDR4 from the system design level, the physical structure level and the protocol level. DDR4 (double data rate 4th gen SDRAM) provides a low operating voltage (1.2V) and a high transfer rate.
