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.

Accelerate SoC Verification, Experts available

SoC designs are growing more complex, not just by the sheer number of transistors that can be packed into one design, but the emergence of different interconnect methods you must use to connect chip internals and to connect to the outside world. Becoming an expert on each of the interconnect protocols is not going to shorten the verification schedules, reduce design productivity and expose design bugs that might only be found when used by the end consumer.

Deciphering the New TileLink Standard

Increasing complexities of processor architectures with limited overall performance scale-up have created a demand for a domain specific architecture to ensure extensive performance scaling. – this is when RISC-V began to gain momentum. RISC-V is gathering widespread attention throughout sectors like datacenter accelerators, mobile & wireless, IoT, etc. for its extensibility. Many industry leaders are beginning to adopt RISC-V for its open source availability that reduces time-to-market and cost effectiveness while at the same time scaling up the overall performance and leaving room for innovation and automation.
