Amazon Web Services, Inc.(AWS) announced that ARM(Arm) will leverage AWS for its cloud use, including the vast majority of its electronic design automation(EDA) workloads. 

Arm is migrating EDA workloads to AWS, leveraging AWS Graviton2-based instances(powered by Arm Neoverse cores), and leading the way for transformation of the semiconductor industry, which has traditionally used on-premises data centers for the computationally intensive work of verifying semiconductor designs. 

To carry out verification more efficiently, Arm uses the cloud to run simulations of real-world compute scenarios, taking advantage of AWS’s virtually unlimited storage and high-performance computing infrastructure to scale the number of simulations it can run in parallel. 

Since beginning its AWS cloud migration, Arm has realized a 6x improvement in performance time for EDA workflows on AWS. 

In addition, by running telemetry(the collection and integration of data from remote sources) and analysis on AWS, Arm is generating more powerful engineering, business, and operational insights that help increase workflow efficiency and optimize costs and resources across the company. 

Arm ultimately plans to reduce its global datacenter footprint by at least 45% and its on-premises compute by 80% as it completes its migration to AWS.

Highly specialized semiconductor devices power the growing capabilities of everything from smartphones, to data center infrastructure, to medical equipment, to self-driving vehicles. 

Each chip can contain billions of transistors engineered down to the single-digit nanometer level(roughly 100,000x smaller than the width of a human hair) to drive maximum performance in minimal space. EDA is one of the key technologies that make such extreme engineering feasible. 

EDA workflows are complex and include front-end design, simulation, and verification, as well as increasingly large back-end workloads that include timing and power analysis, design rule checks, and other applications to prepare the chip for production. 

These highly iterative workflows traditionally take many months or even years to produce a new device, such as a system-on-a-chip, and involve massive compute power. Semiconductor companies that run these workloads on-premises must constantly balance costs, schedules, and data center resources to advance multiple projects at the same time. 

As a result, they can face shortages of compute power that slow progress or bear the expense of maintaining idle compute capacity.

By migrating its EDA workloads to AWS, Arm overcomes the constraints of traditionally managed EDA workflows and gains elasticity through massively scalable compute power, enabling it to run simulations in parallel, simplify telemetry and analysis, reduce its iteration time for semiconductor designs, and add testing cycles without impacting delivery schedules. 

Arm leverages Amazon Elastic Compute Cloud(Amazon EC2) to streamline its costs and timelines by optimizing EDA workflows across the wide variety of specialized Amazon EC2 instance types. 

For example, the company uses AWS Graviton2-based instances to achieve high-performance and scalability, resulting in more cost-effective operations than running hundreds of thousands of on-premises servers.

On top of the cost benefits, Arm leverages the high-performance of AWS Graviton2 instances to increase throughput for its engineering workloads, consistently improving throughput per dollar by over 40% compared to previous generation x86 processor-based M5 instances. 

In addition, Arm uses services from AWS partner Databricks to develop and run machine learning applications in the cloud. 

Through the Databricks platform running on Amazon EC2, Arm can process data from every step in its engineering workflows to generate actionable insights for the company’s hardware and software groups and achieve measurable improvement in engineering efficiency.
