Helium virtual and hybrid studio realize high-performance pre silicon software verification under virtual and hybrid platforms, helping 5g, mobile, automotive, super large-scale computing and other markets.

Shanghai, China, September 23, 2021 – cadence (US cadence Corporation, NASDAQ: CDNs) released cadence today ® Helium ™ Virtual and hybrid studio platforms accelerate the creation of virtual and hybrid prototypes of complex systems. Helium studio enables users to start software and hardware collaborative verification and debugging very early, fully supports platform integration, realizes the creation and error correction of virtual models, and presets rich component libraries of virtual models and hybrid adapters. For SoC with virtual or hybrid model, compared with simple RTL model, this system not only has several orders of magnitude improvement in simulation speed, but also can realize early software development before RTL is available.

The new helium studio is similar to palladium in architecture design ™ Z2 enterprise hardware simulation platform, protium ™ X2 enterprise prototype verification platform and xcelium ™ Native integration of cadence verification engine such as logic simulation platform. Before the completion of RTL, helium studio can verify the embedded software and firmware in pure virtual and hybrid modes to realize the rapid development of the system.

When developing next-generation mobile, automotive and very large-scale computing applications, engineers need to verify the software on the silicon front platform to ensure the success of the design and meet the time to market. Helium Studio allows designers to build high-quality virtual and hybrid SOC prototypes. Thanks to the native integration of software engine with palladium Z2 platform and protium x2 platform, helium Studio provides software developers with a unified debugging experience from virtual model to RTL. Specific features include:

·Virtual Studio: provides GUI based platform assembly to build the platform quickly and correctly, so as to realize early software startup. After the platform is assembled, virtual studio can be used to execute and debug software stack and hardware design.

·Hybrid Studio: by using the preset component library of rich hybrid adapters, transaction processors and intelligent memory, the system can help designers quickly create hybrid configurations. The communication between components has been specially optimized, with the highest throughput and native integration with palladium and protium platforms. The new gearshift technology supports the software to build a hot switch from virtual to RTL, which can not only give play to the high speed of the virtual engine, but also switch to the RTL engine on demand to ensure accuracy.

·Virtual model component library: the system provides a comprehensive virtual model library, using the latest arm ® Technical model portfolio, including support for the armv9-a series. Designers can access multiple reference and entry-level virtual or hybrid platforms, and can run the latest Linux and Android operating systems on them, so as to accelerate the construction of the new platform.

·Embedded software debug: the system provides unified and comprehensive multi-core and multi process debugging of embedded software. A single debugger can support the cooperation of software and hardware on virtual platform and RTL platform at the same time, so that designers can better control and view the software. The native integration of software engine with virtual and RTL engine ensures the synchronization of software and hardware debugging.

“Simultaneous verification of RTL and early development of embedded software is the key to ensure the successful design of new generation mobile, automotive and super large-scale SOC,” said Paul Cunningham, senior vice president and general manager of systems and verification division of cadence, “The new helium studio gives full play to the advantages of palladium and protium, the two best verification engines in the industry, which help the rapid development of software and become the benchmark of power consumption and performance verification. This new system will provide a unified platform for designers and accelerate the overall improvement of verification swallowing rate.”

The new helium virtual and hybrid studio are part of the whole process of cadence verification, including palladium Z2 hardware simulation acceleration platform, protium x2 prototype verification platform, xcelium simulation platform and jaspergold ® Formal verification platform and vmanager ™ Verify the management platform. Under the same conditions of unit investment and unit time, cadence has the highest verification and commissioning throughput in the whole verification process. Helium studio supports the company’s intelligent system design in the whole process of and verification ™) Strategy to help system innovation.

Customer feedback

“The ability to start and run the industry benchmark test program on the latest GPU and SOC before silicon is the key to ensure one-time success and meet the time to market requirements. With cadence helium virtual and hybrid studio, which are natively integrated with palladium and protium platforms, we have successfully found and repaired multiple software and RTL errors in front of silicon. The impact of hybrid platform Several levels of throughput improvement allows us to perform long-time tests in the pre silicon environment. Helium studio’s unique gearshift technology allows us to dynamically realize the hot switching from virtual to RTL, which not only provides fast enough early software development, but also realizes the accuracy of RTL on demand. Helium studio’s embedded software debugging function realizes the collaborative verification of software and hardware without considering software and hardware Is the running environment a virtual core or an RTL core? “

“Our team has been looking for new methods to move software development and debugging forward to meet the increasingly tight market demand for 5g terminal equipment solutions. We use the new cadence helium virtual and hybrid studio. In addition to verifying the physical layer of 5g design, we can also advance the software protocol code debugging of L2 / L3 layer by 2 months. Helium studio runs at a mixed mode It will speed up 50-100 times to support rapid software code iteration. It is natively integrated with the powerful palladium system to ensure a smooth transition from virtual to hybrid to full RTL software and hardware co simulation, which helps us advance the design planning by several months. “
