Ecosystem Partners Shift Left with Intel for Faster Time-to-Market
By Michael G., published on May 28, 2019
Intel’s Pre-Silicon Customer Acceleration (PCA) program scales innovation across all operating environments using the Simics® virtual platform as a primary technology. The program helps customers develop, test, tune, and optimize mission-critical code, including operating systems, BIOS, and firmware, before silicon is ready—shifting those efforts earlier (to the left) in customers’ product development cycles. The business result is faster time-to-market (TTM) for hardware and software developers across the Intel ecosystem.
For Intel’s customers to achieve faster product releases, new and complex features in Intel® silicon need a software development runway. In addition, Intel needs close collaboration and feedback on the system software we deliver to customers. Intel’s Pre-Silicon Customer Acceleration (PCA) program accomplishes those goals as it aims to enable each mission-critical software stack to boot and run on Day 1 at customer platform power-on, significantly reducing customer time-to-launch.
Our customers face time-to-market (TTM) challenges as they contend with increased hardware complexity, competitive pressure, software/hardware integration, and initially limited hardware availability. The PCA program speeds-up TTM by driving parallelization of each customer’s software development process with Intel’s own product development.
That effort requires the PCA team to engage early in Intel’s own development process to understand and incorporate customer requirements, upfront. Primary deliveries to customers take place between nine months to a year ahead of first silicon samples and continue throughout the development process.
The PCA program supports dozens of original equipment manufacturers (OEMs) and original device manufacturers (ODMs), along with major independent firmware vendors (IFVs), operating system vendors (OSVs), and independent software vendors (ISVs). The PCA team also partners with electronic design automation (EDA) houses to support more sophisticated solutions at customer sites.
By supporting IFVs, OSVs and others that deliver to our customers, we help complete early readiness of the entire software stack. The PCA team focuses on ensuring each customer’s system software is ready. That includes layers such as:
Intel® firmware and reference BIOS
Customer and third-party BIOS and firmware
Peripheral firmware and drivers
OS and device drivers
Lower-level middleware
The Simics virtual platform (VP) is the primary solution the PCA team uses to represent Intel’s silicon well ahead of its actual arrival. Each VP model is register-accurate, allowing customers to develop their system and platform software on top. That allows for a smooth transition to hardware. Customers continue to use this developer-friendly VP environment for software development, continuous integration, and testing, even after silicon arrives.
HPE Uses Simics to Deliver New Products Faster than Ever
Hewlett Packard Enterprise (HPE) is an industry leader in servers, storage, wired and wireless networking, converged systems, software, services and cloud. As one of the top customers for Intel’s Data Center Group, HPE relies on Simics VP software for their BIOS/firmware development, continuous integration, and regression testing.
“Server market dynamics are changing quickly, and we need to react with new products faster than ever,” says HPE Senior Firmware Development Manager, James Bodner. “Not hitting a TTM launch costs in lost revenue, and firmware complexity has become the leading driver of program schedules.” Together with challenges in getting early silicon in volume, those issues drive HPE’s need to do more pre-silicon.
According to Bodner, the heart of HPE innovation and server products is the HPE Integrated Lights-Out (iLO) Baseboard Management Controller (BMC). It represents 20 Years of HPE value add, and HPE has accumulated 20 years of dependencies between BIOS and the iLO BMC. HPE and Intel collaborated on how the model could be built for this effort.
“We started laying out a framework a year ago. The first-generation goal in 2018 was to get a basic model, but it still required significant firmware work,” says Bodner. “We’re extending the model interfaces to include the HPE non-volatile memory store, and we’re on-track to get to a fully functional iLO model running BMC firmware and BIOS, using real firmware with no modifications.”
Bodner added that HPE already had its own simulation environment with millions of lines of code already written. “To avoid starting over from scratch, HPE ASIC developers came up with a way to translate the HPE simulation model to Simics, greatly accelerating the effort. We’re already booting Intel’s next-generation ‘Whitley’ platform to Linux* on a Simics VP with the iLO model, using the HPE BIOS. We have a global team of more than 20 developers actively using the Simics VP to develop and test changes, and we’ve ported and tested 200+ changes to Whitley reference code.”
Some recent HPE power-on successes with Simics VP software include:
Booted HPE Whitely based platform with future “Ice lake” CPU to UEFI Shell in 12 hours
Booted HPE Whitely based platform with future Ice lake CPU to Linux in 24 hours
Only three minor code fixes necessary to boot from Simics VP to real silicon
“These milestones represent significant improvement from previous generation power-on events: from days to hours!” says Bodner. “Our future initiatives include tying Simics into HPE’s continuous integration framework, to ensure every change is tested before it is committed, and to improve quality by finding issues before they get into source control—to stop the problem before it is released.”
The AMI Ecosystem Shifts Left with Simics
American Megatrends International LLC (AMI) is the world’s leading provider of BIOS and UEFI firmware and out-of-band server management solutions. AMI CEO Sanjoy Maity shared his thoughts on the synergy between Intel Simics initiatives and AMI’s vision.
“AMI has been using Simics for a few generations of Intel silicon,” says Maity. “AMI enables customers with Simics boot as soon as it is available from Intel. That enables customers to adapt their IP to the new project codebase.”
Maity listed several ways that AMI uses Simics VPs:
Heavily used before power on
Useful for early code development
Understand new release candidate (RC) code design
Triage and fix issues while adopting new silicon code
Integrate and validate AMI IP pre-power-on
Useful for some issue triage post power-on
Simulate various CPU, memory and PCIe combinations for validation and issue triage
“Simics is the perfect companion for today’s ‘Agile Development Model’ because it brings higher efficiency, better visibility, and adaptability,” Maity adds. “We use it for delivery and continuous integration.”
Maity points out that increasing efficiency in development requires AMI to do three things: increasing access to the hardware; collaborative development; and automating development through DevOps. “This means build more hardware at an earlier stage, which could result in a ridiculously high investment in hardware.”
Simics VPs solve that problem for AMI in four ways, he says:
Dramatically reduces hardware cost—the investment at the front-end of development
Virtually replaces the need for hardware at the engineer’s desk
Enables the Agile Development
Fits into AMI’s continuous integration/continuous delivery (CI/CD) infrastructure
“However, Simics has much broader potential beyond just silicon modeling,” Maity observes. “Simics can help in full server product development. It can extend simulations to all silicon features, and the ecosystem can benefit from full platform simulation. Simics can be instrumental to shorten time-to-market. So, the sky is the limit! Simics can shift left the entire ecosystem.”
The next steps envisioned by Maity include working with Intel as an ecosystem partner and working with OEMs and ODMs on Simics-enabled platform development. “The goal would be to help simulate end-user deployment scenarios and help triage issues that are difficult to reproduce on physical hardware. This would enable cloud and hyperscale customers to reduce complex hardware dependencies, and it would help OEMs and ODMs to adopt and heavily use Simics for development, validation and support.”
Use Simics VP Software to Shorten Your TTM
Simics enables developers to simulate anything, chip to system, and get the access, automation, and collaboration tools required for Agile development practices.
