22 Jan Avery Design Announces CXL™ 2.0 VIP
TEWKSBURY, Mass.–(BUSINESS WIRE)–Avery Design Systems, leader in functional verification solutions today announced availability of CXL 2.0 VIP. Computer Express Link™ (CXL) is an open industry-standard interconnect offering coherency and memory semantics using high- bandwidth, low-latency connectivity between host processor and devices such as accelerators, memory buffers, and smart I/O devices
Avery provides a complete System Verilog/UVM verification solution including models, protocol checking, and compliance test suites for PCIe® 5.0 and CXL 2.0/1.1 for CXL host, Type 1-3 devices, switches, and retimers. The CXL 2.0 VIP adds key CXL 2.0 features including
MLD for memory pooling including persistent memory
Native PCIe endpoint enumeration
Significant compliance tests update
The CXL 2.0 VIP also includes key features including
Additional VIPs supporting key SoC interface protocols – CPI, CXS, LPIF
Automatic CXL bus enumeration
Dynamic configuration of VIP for legacy PCIe, CXL 2.0 or CXL 1.1 including CXL device types 1-3
Full home agent with cache and snoop filter to support Type 1-2 devices and high-level load/store initiator semantics
Realistic traffic arbitration among CXL.IO, CXL.Cache, CXL.Mem and CXL control packets.
Unified user application data class for both pure PCIe and CXL traffic.
“We are excited to be working with leading server processor, managed DRAM and storage class memory (SCM) buffers, switch/retimer, and IP companies who are rapidly growing the CXL datacenter ecosystem in 2021 and beyond,” said Chris Browy, vice president sales/marketing of Avery. “Our collaboration with IP companies is also critical by creating a best-in-class, robust, pre-validated CXL 2.0 IP controller and PHY solutions and streamlines the design and verification process and fosters the rapid adoption of the CXL standard by the industry.” Besides CXL Avery supports the main cache coherent VIPs including CCIX®, AMBA® 5 CHI-E and ACE, and Gen-Z™.
“Our collaboration with Avery has been very fruitful in making sure that our CXL design IP (COMPEX™) is fully verified and compliant to the CXL specifications,” said Ravi Thummarukudy, CEO of Mobiveil. “Verifying COMPEX with Avery VIP enabled us to successfully validate it with Intel’s CXL host platform quickly. Avery has been on the leading edge when it comes to delivering the latest Industry compliant VIP solutions such as CXL, PCIe and NVMe etc. solutions. Our joint efforts have significantly reduced the time it takes for our mutual customers to integrate Design IPs in to their SOC designs and reducing their time to market and ensuring first time silicon success.”
Mobiveil’s CXL controller IP (COMPEX™) is a highly configurable, low-latency CXL controller that supports host and device modes for several high-performance applications, such as data center accelerators, memory expanders, artificial intelligence/machine learning and special applications. The COMPEX controller IP is designed for CXL 2.0 specification and supports host and type 1, type 2 and type 3 devices. COMPEX also supports dual mode where it can be configured to operate either as a host or any of the device types.
COMPEX supports up to 16 lanes on a flex bus interface and is compliant with the PIPE 5.2 specification. It provides a simple packet-based interface-to-user logic that supports 128-bit, 256-bit and 512-bit data path widths and provides a low-latency path for easy integration into a customer ASIC. An implementation can choose one of the datapath widths based on the number of lanes and target technology to get low-latency and optimized power consumption from COMPEX controller. For CXL.io, COMPEX uses Mobiveil’s PCI-SIG® compliant GPEX™ controller and adds highly efficient and configurable CXL.mem and CXL.cache layers for a low-latency coherent path.
