We recently published the VIP Newsletter for Q3 2018, containing trending topics, leading solutions, in depth technical articles, videos, webinars, and updates on next generation protocols. The newsletter covers content on DFI 5.0 for DDR5/LPDDR5, NVMe 1.3, USB 3.2, PCIe 5.0, next generation gaming displays, MIPI CSI-2 v2.1 for Automotive and IoT, and Verdi performance analyzer and protocol debug. In case you missed the latest buzz on Verification IP, you can read it here.
This year’s PCI-SIG Developers Conference took place at the Santa Clara Convention Center on June 5-6. Synopsys provided several demos covering the PCIe 5.0 Integrated IP Core, PHY, and Verification IP & source code Test Suites. There was a constant pool of inquisitive attendees interacting with our PCIe design and verification experts regarding the demos.
The growth of datacenter, storage, automotive and other emerging market applications is driving the development of next-generation memory technologies – DDR5, LPDDR5. Like their predecessors, the latest memory technologies also use DFI, a standard interface between memory controller and PHY, to reduce the integration cost and increase performance and data throughput efficiency. DFI also has evolved along with the memory technologies, and next generation DFI 5.0 is here to ensure higher performance in the systems using DDR5/LPDDR5. In this blog, we will discuss the new features of DFI 5.0 specification.
With the rise of cloud computing and large scale data centers, both developers and consumers are demanding for more efficient ways to rapidly access their data. Seeing the advantage of its high performance, the storage industry is quickly adopting the Non-Volatile Memory Express (NVMe) standard. The NVMe™ standard continues to push the storage envelope with version 1.3 and beyond in all types of computing environments from mobile to data center. One of the key features of the NVMe™ standard is its ability to handle virtualization.
New applications like Cloud Computing, Artificial Intelligence, Autonomous cars, Augmented reality, Embedded vision are driving stricter requirements around memory performance and power efficiency. Memory is central to these systems, that require high bandwidth and speed along with lower power and lower cost. With these emerging market needs, the memory industry started to move from planar (2D) DRAMs to wide I/O or a 3D technology TSVs (Through Silicon Vertical interconnect access) such as HBM (high bandwidth memory). For more insight on HBM, read our blog “Next Generation Memory Technology for Graphics, Networking and HPC.” Low Power DRAM technology, evolved to the fifth-generation(LPDDR5) to deliver significant reduction in power and extremely high bandwidth as compared to LPDDR4. In this blog, we discuss LPDDR5 new features based on our understanding from collaboration with memory vendors and early adopters of Synopsys VIP over last 2 years.
SoC performance is a key competitive advantage in the marketplace, and the choice and configuration of protocol IP and interconnects is geared towards maximizing said performance. A case in point is the use of HBM (High Bandwidth Memory) technology and memory controllers. Currently in its third generation, HBM boasts of high-performance while using lesser power in a substantially smaller form factor than DDR. That said, how do teams ensure that the performance is delivered in the context of their SoC design?

PCIe is a multi-layered serial bus protocol which implements dual-simplex link. It provides high speed data transfer and low latency owing to its dedicated point to point topology. To accelerate verification and device development time for PCIe based sub-systems, PIPE (PHY Interface for the PCI Express) architecture was defined by Intel. PIPE is a standard interface defined between PHY sub-layer (PCS – Physical Coding sub-layer) and MAC (Media Access Layer).
Is your latest NVMe design taking advantage of Streams? Adoption of this new NVMe technology is gaining momentum with Synopsys customers. Streams are part of the new, optional, Directives feature introduced in the NVMe 1.3 specification. Directives allow the passing of metadata between hosts and controllers via existing NVMe commands. Streams are unique in that they are the only I/O based Directive available in the 1.3 specification.
In June 2017, PCI-SIG announced the new PCI Express 5.0 specification, at the PCI-SIG DevCon. The new version of the specification doubled bit rate to 32GT/s per lane providing about 128GB/s bandwidth for a x16 Link (16 lanes). The chart below provides a comparison of bit-rate and bandwidth for the different PCIe Generations.
