Cloud offers a proven way to accelerate end-to-end chip design flows. In a previous blog, we demonstrated the inherent elasticity of the cloud, showcasing how front-end simulation workloads can scale with access to more compute resources. Another benefit of the cloud is access to a powerful, modern and global infrastructure. On-prem environments do a fantastic job of meeting sustained demand but Electronic Design Automation (EDA) tooling upgrades happen much more frequently (every six to nine months) than typical on-prem data center infrastructure upgrades (every three to five years). 

What this means is that your EDA tool can provide much better performance if given access to the right infrastructure. This is especially useful in certain phases of the design process.

Take for example, a physical verification workload. Physical verification is typically the last step in the chip design process. In simplified terms, the process consists of verifying design rule checks (or DRCs) against the process design kit (PDK) provided by the foundry. It ensures that the layout produced from the physical synthesis process is ready for handoff to a foundry (in-house or otherwise) for manufacturing. Physical verification workloads tend to require machines with large memories (1TB+) for advanced nodes. Having access to such compute resources enables more physical verification to run in parallel, increasing your confidence in the design that is being taped out (i.e., sent to manufacturing).

At the other end of the spectrum are functional verification workloads. Unlike the physical verification process described above, functional verification is normally performed in the early stages of design and typically requires machines with much less memory. Furthermore, functional verification (dynamic verification in particular) accounts for the most time (translating directly to the availability of compute) in the design cycle. Verifying faster, an ambition for most design teams, is often tied to availability of right-sized compute resources. 

The intermittent and varied infrastructure requirements for verification (both functional and physical) can be a problem for organizations with on-prem data centers. On-prem data centers are optimized for maximizing utilization—this does not directly address access to right-sized compute to deliver the best tool performance. Even if the IT and Computer Aided Design (CAD) departments choose to provision additional suitable hardware, the process of provisioning, acquiring and setting up new hardware on-prem typically takes months for even the most modern organizations. A “hybrid” flow that enables use of on-prem clusters most of the time, but provides seamless access to cloud resources as needed would be ideal.

Hybrid chip design in action

You can improve a typical verification workflow simply by utilizing a hybrid environment that provides instantaneous access to better compute. To illustrate, we chose a front-end simulation workflow, and designed an environment that replicates on-prem and cloud clusters. We also took a few more liberties to simplify the environment (described below). The simplified setup is provided in a GitHub repository for you to try out.

In any hybrid chip design flow, there are a few key considerations:

1. Connectivity between on-prem infrastructure and the cloud: Establishing connectivity to the cloud is one of the most foundational aspects of the flow. Over the years, this has also become a very well-understood field, and secure, high availability connectivity is a reality in most setups. 
   
   In our tutorial, we represent both on-prem and cloud clusters as two different networks in the cloud where all traffic is allowed to pass between these networks. While this is not a real-world network configuration, it is sufficient to demonstrate the basic connectivity model.
   
2. Connection to license server: Most chip design flows utilize tools from EDA vendors. Such tools are typically licensed, and you need a license server with valid licenses to operate the tool. License servers may remain on-prem in the hybrid flow, so long as latency to the license server is acceptable. You can also install license servers in the cloud on a Compute Engine VM (particularly sole-tenant nodes) for lower latency. Check with your EDA vendors to understand if you can rehost your license services in the cloud.
   
   In our tutorial, we use an open source tool (Icarus Verilog Simulator) and therefore, do not need a license server.
   
3. Identifying data sources and syncing data: There are three important aspects in running EDA jobs: the EDA tools themselves, the infrastructure where the tools run, and the data sources for the tool run. Tools don’t change much, and can be installed on cloud infrastructure. Data sources, on the other hand, are primarily created on-prem and updated regularly. These could be SystemVerilog files that describe the design, the testbenches or the layout files. It is important to sync data between on-prem and cloud to maintain parity. Furthermore, in production environments, it’s also important to maintain a high-performance syncing mechanism.
   
   In our tutorial, we create a file system hierarchy in the cloud that is similar to one you’d find on-prem. We transfer the latest input files before invoking the tool.
   
4. Workload scheduler configuration and job submission transparency: Most environments that leverage batch jobs use job schedulers to access a compute farm. An ideal environment finds the balance between cost and performance, and builds parameters in the system to enable predictive (and prescriptive) wrappers to job schedulers (see picture below).
   
   In our tutorial, we use the open-source SLURM job scheduler and an auto-scaling cluster. For simplicity, the tutorial does not include a job submission agent.

Other cloud-native batch processing environments such as Kubernetes can also provide further options for workload management.

Our on-prem network is called ‘onprem’ and the cloud cluster is called ‘burst’. Characteristics of the on-prem and burst clusters are specified below:

Once set up, we ran the OpenPiton regression for single and two-tile configurations. You can see the results below:

Regressions run on “burst” clusters were on average 30% faster than on “onprem”, delivering faster verification sign-off and physical verification turnaround times. You can find details about the commands we used in the repository. 

Hybrid solutions for faster time to market

Of course, on-prem data centers will continue to play a pivotal role in chip design. However, things have changed. Cloud-based, high performance compute has proved itself to be a viable and proven technology for extending on-prem data centers during the chip design process. Companies that successfully leverage hybrid chip design flows will be able to better address the fluctuating needs of their engineering teams.

State and local government (SLG) agencies are reeling from a combination of unbudgeted COVID-related expenses and reduced tax revenue caused by unemployment and business closures. Any way you look at it, the situation is challenging. To understand how SLG agencies are coping, Google Cloud collaborated with MeriTalk to survey 200 SLG IT and program managers, uncovering some revealing trends in SLG technology innovation. Unsurprisingly, approximately 84% of SLG organizations report making budgetary tradeoffs to bridge funding the gaps the ongoing pandemic has created. 

However, researchers discovered a silver lining: The pandemic has also been a catalyst to modernize the legacy infrastructure in states and cities. The majority of survey respondents (88%) reported that their agency made greater modernization progress this past year than in the prior 10 years.

Walking a tightrope between innovation and budget pressure

According to 89% of state and local leaders, now is the time to invest in technology modernization. But 80% are experiencing a funding gap due to unbudgeted expenses related to the pandemic and declining tax revenue, which makes finding that balance between innovation and budget a serious challenge.

Some agencies are achieving the impossible, though. For example, the City of Pittsburgh Department of Innovation and Performance is working with Google Cloud to migrate  and modernize its legacy IT infrastructure. By decommissioning their data center and moving to Google Cloud, the city can build new data analytics tools to drive smart city initiatives and create entirely new applications to improve digital service delivery for its residents. As a result, the city will save costs, abandon its brittle legacy IT structure, and create a cloud-based technology platform for the future—becoming the region’s leader in cloud-native software development.

Google Cloud is enabling the city’s IT team by curating and delivering our certification training at no cost. The program includes live training sessions as well as on-demand training. 

Bridging funding gaps

In their drive to modernization, many SLG leaders are turning to grants as an important source of funding. Approximately 84% of those surveyed report making tradeoffs to bridge funding gaps, such as moving resources away from operations and maintenance (37%), increasing reliance on pandemic-related funding (31%), and delaying internal modernization efforts to enable remote work for employees (29%). One way that states are dealing with this tension between budget gaps and the need for innovation is to turn to Google Cloud for cost savings and improved capabilities.

For example, Google Cloud is helping the State of West Virginia innovate and enhance IT security despite decreased state funding. The state entered a multi-year agreement to ensure full access to enterprise-level Google Workspace capabilities for 25,000 state employees, keeping the state at the forefront of technology advancements at a projected cost savings of $11.5 million.

Similarly, Google Cloud helped build the Rhode Island Virtual Career Center to help the state’s constituents get back to work. Using familiar productivity tools within Google Workspace, employees can access new career opportunities quickly, while employers can reach more candidates. Skipper, the CareerCompass RI bot, uses data and machine learning to connect Rhode Islanders with potential new career paths and reskilling opportunities.

Enhancing services

Google Cloud is also helping agencies enhance services, including working with the State of Illinois to get unemployment funding to constituents in need.The state is using Contact Center AI to rapidly deploy virtual agents that help more than 1 million out of work citizens file unemployment claims faster. Capable of engaging in human-like conversations, these intelligent agents provide constituents with 24/7 access and enable government employees to focus on more complex, mission-critical tasks—such as combating fraud. In summer 2020, the virtual agents handled more than 140,000 phone and web inquiries per day, including 40,000 after-hours calls every night. The state anticipates an estimated annual savings of $100 million from the solution, which was deployed in just two weeks.

Working with Google, Ohio also uncovered $2 billion in fraudulent unemployment claims. We will continue to partner with the state to find fraudulent claims, and prioritize the processing of legitimate claims.

 Focusing on cybersecurity

Despite expanding security threats topping NASCIO’s list of 2021 State CIO priorities, more than one in three IT managers (35%) say their organization reduces security measures to expedite timelines. Partnering with Google Cloud has enabled many agencies to enhance their security measures while modernizing and staying within budget, investing in support for remote work devices, digital services for residents, and cybersecurity.

NYC Cyber Command works with city agencies to ensure systems are designed, built, and operated in a highly secure manner. NYC3 followed a cloud-first strategy using the Google Cloud Platform. The virtual operations demanded by the pandemic have increased the importance of security and compliance in SLG. Google Cloud is committed to act as a security transformation partner and be the trusted cloud for public sector agencies. 

Finally, to strengthen public and private partnerships, SLG organizations told MeriTalk that they need vendor partners to support modernization efforts for flexibility and collaboration (46%), need innovation-focused leadership groups to help balance technology needs with budget constraints (41%), and they expect significant returns on investments in cloud computing (38%), and data management/analytics (33%).

Google Cloud is helping SLG customers across the country invest in innovation to walk the tech tightrope—balancing innovation and budgets—and helping to build a more resilient future. Visit the State and Local Government solutions page to learn more.

If you happened to miss our last few episodes, we recommend checking out our introduction blog to the series for what you missed. Let’s dive into our latest episodes, discussing the impact of open source and novel security challenges in multicloud environments.

Episode #5: ‘The intersection of open source and multicloud’

Open source technology has been an integral part of computing since its earliest era, predating even the birth of technology hubs like Silicon Valley. Open source projects have been responsible for giving us some of the most popular software in the world, such as Mozilla Firefox and the operating system Linux.

In the fifth episode, we sat down with Mike Coleman, Cloud Developer Advocate at Google Cloud, and took a closer look into the history of open source technologies, the role they play in a multicloud world, and the developer perspective on using these technologies to do their work.

The concept of multicloud anchors on the ability to run workloads across clouds and being able to pick the providers that are best suited for specific parts of workloads. Adopting open source technologies and languages empower companies to use the tools they need, regardless of cloud provider, without the fear of getting locked into a specific provider.

“As you think about moving across different environments, whether that be cloud to cloud, or developer desktop to ultimate destination, whether that be your data center or the cloud. Open source software allows you to do that…and multicloud is just an extension of that. This idea that I need to run the same software wherever I go.” — Mike Coleman, Cloud Developer Advocate at Google Cloud

If you’ve ever wanted a developer’s take on the impact of multicloud and the influence of open source in software development and digital transformation trends, you’ll want to tune into this episode.

Episode #6: ‘Novel challenges in security with multicloud’

In the sixth episode of the series, we chatted with Dr. Anton Chuvakin, Security Advisor at Office of the CISO at Google Cloud, about how security leaders and architects are shifting away from traditional security models, which are increasingly insufficient for multicloud environments.

As more organizations adopt multicloud approaches, the question of how to maintain security in these complex environments and the increasing burden on SecOps teams is top of mind. As Dr. Chuvakin noted, the challenges in the cloud facing more traditional teams range from types of telemetry and logs to volumes and lack of clarity on detection use cases. However, these issues intensify when extended to include multiple clouds, where learning how to do something on one provider may be completely different on another.

“If you end up multicloud, you need to know public cloud and how it works at a better level than you would if you’re going to a single provider. Just like if you’re trying to repair three cars, you need to first learn how to repair cars. You need to have more cloud knowledge to do multicloud, not less. You need to have more powerful superpowers in the public cloud computing area because you can’t just learn one provider and call it a day.” — Dr. Anton Chuvakin, Security Advisor at Office of the CISO at Google Cloud

During the discussion, he offered three tips for tackling multicloud security:

1. Learn cloud more, not less if you’re going multicloud. Multicloud requires more cloud knowledge because you can’t learn a single provider and call it a day. You’ll need to understand the differences in order to be able to secure multiple cloud environments.
2. Focus on learning cloud identity management and how it compares to your traditional identity management service functions. Start with identifying the differences and similarities in what you see in one cloud and then continue with other clouds you use.
3. Explore where your threat areas change in cloud environments when you plan detection and response activities to understand if your detection is covered across clouds.

If your organization is embracing multicloud, this is a great episode to listen and learn more about cloud security, the primary considerations and challenges facing security teams, and some helpful best practices for thinking about security in multicloud environments.

We’ll be sharing the latest topics and episodes with you every month in this blog series. Until next time.
