Addressing Heterogenous Verification and Validation Requirements for Compute Express Link (CXL) Designs Using Synopsys Protocol Continuum
Data is the new fuel powering critical use-cases for cloud /edge computing, and advances in AI. All aspects of data handling – gathering, storing, moving, processing, and dispersing – pose unique design implementation and verification challenges. The need for heterogenous computing has given exponential rise to application specific accelerators, pushing the industry to come up with a solution for efficient data handling and resource utilization. CXL is a processor interconnect protocol designed to support high bandwidth, low-latency interface from CPU to workload accelerators, maintaining memory coherency across heterogeneous devices, while addressing security needs of the user.

Demystifying PCIe PIPE 5.1 SerDes Architecture
Artificial intelligence and machine learning are rapidly penetrating a wide spectrum of devices, driving the re-architecture of SoC designs and requiring more memory space and higher bandwidth to transfer and process data. This change requires higher speed interfaces and wider buses, paving the path for enhancements in the latest PCIe protocol specifications, as well as upgrades in PIPE (PHY Interface for the PCI Express) specification as the preferred PHY interface.

Managing NVMe Verification Complexity
From inception, NVMe was designed to support multiple hosts accessing shared media. Early implementation included PCIe in-the-box devices such as Endpoint(EP), Root complex(RC) and Root complex integrated endpoint(RCiEP); over time, Cloud and Storage infrastructure created a need for remote storage.
PCIe 5.0 Equalization Modes: Reducing Link Bring-Up Time
Billions of internet-connected devices and data-intensive real-time applications are expected to appear on the market in the near future and 100 Gigabit Ethernet (GE) speeds, common in data centers today, will just not be fast enough to handle the bandwidth. Therefore, we’re already anticipating the need for data center operators to migrate their networks from 100 GE to 400 GE, creating demand for faster memory and faster serial bus communications.

De-mystifying CXL: An overview
As Data Center and Artificial Intelligence applications take center stage , last few years have seen the advent of various high bandwidth interconnect technologies. Compute Express Link (CXL), is an aspiring new interconnect technology for high bandwidth devices such as accelerators with memory, high density compute cards, and GPU comprised accelerators. The specification is defined by CXL Consortium https://www.computeexpresslink.org/. Synopsys has developed a comprehensive CXL verification subsystem, being already used by Early Adopters planning to release their first CXL applications. CXL verification subsystem leverages industry popular Synopsys PCI Express Verification IP. Synopsys recently introduced Industry’s first CXL IP solution. For more details refer Synopsys Delivers Industry’s First Compute Express Link (CXL) IP Solution for Breakthrough Performance in Data-Intensive SoCs.
