Shulou(Shulou.com)11/24 Report--

Shanghai Hejian Industrial Software Group Co., Ltd.(hereinafter referred to as "Hejian Industrial Software") and Beijing Huada Jiutian Technology Co., Ltd.(hereinafter referred to as "Huada Jiutian") jointly announced that they will jointly build a joint solution of digital-analog hybrid design and simulation EDA. UniVista Simulator (UVS), a commercial-level high-efficiency digital verification simulation solution based on the independent intellectual property rights of UniVista, and Empyrean ALPS® (ALPS), a high-speed and high-precision parallel transistor-level circuit simulation tool based on the independent intellectual property rights of Huada Jiutian, create a complete analog-to-digital hybrid design simulation solution to help Chinese chip design enterprises solve the challenges of analog-to-digital hybrid simulation.

Based on the in-depth cooperation between HeJian Engineering Software and BGI, the two parties will jointly provide integrated and complete mixed-signal design solutions for Chinese chip design companies, combining BGI's Empyrean ALPS® analog simulator with HeJian Engineering Software's UniVista Simulator digital simulator to form a joint solution, enabling enterprises to simulate and optimize mixed-signal chip designs. Through the digital-analog hybrid design simulation scheme, various situations of the chip in the actual working environment are verified, and the correctness of the chip working in various scenarios is ensured, including the influence of noise, interference, temperature change and other factors on the chip performance. In addition, the digital-analog hybrid simulation can also help designers optimize the circuit structure and parameter setting of the chip, and improve the performance and reliability of the chip. With this solution, customers can speed up the chip development process, improve the functional verification of the design, and verify the correctness and reliability of the chip design.

The solutions developed by the two parties integrate their respective technical accumulation and advantages in digital signal logic simulation and analog signal transistor-level simulation to help customers solve key problems in mixed-signal chip design. The application fields will cover various analog microcontroller applications such as industrial control, automotive electronics, power management and other markets.

A hybrid design simulation scheme includes:

See software UVS high performance digital simulator, can fully support SystemVerilog and UVM. The integrity of its VPI interface supports analog simulators based on standard VPI mode access to quickly connect UVS to realize digital-analog hybrid simulation. In addition, UVS improves the efficiency of customer digital-analog hybrid simulation by enhancing the support of wreal model.

Empyrean ALPS®, a high-speed and high-precision parallel transistor-level circuit simulation tool of Huada Jiutian, has complete SPICE accuracy, innovative intelligent matrix solving algorithm and unique multi-core parallel simulation technology, which significantly improves SPICE simulation capacity and performance while ensuring simulation accuracy, and supports circuit simulation of tens of millions of components.

As a leading enterprise of domestic EDA, BGI Jiutian cooperates with innovative EDA companies to jointly build technology innovation and joint tool platform, aiming to provide more complete EDA solutions for Chinese chip design companies, enhance the design and development capabilities of digital-analog mixed signal chips, and accelerate the R & D and iteration of EDA tool solutions based on complete digital-analog mixed signal design processes. At the same time, the introduction of this joint scheme has innovative significance for realizing the full localization of EDA solutions in the field of analog and digital mixed signal simulation.

Liu Jingjun, vice president of Hejian Software, said: "In the process of supporting customer digital simulation projects, Hejian Software will constantly encounter customer demands involving mixed simulation. We are pleased to have an in-depth cooperation with Huada Jiutian to strengthen joint development based on VPI interface to achieve mixed simulation of UVS and ALPS, improve the efficiency and accuracy of mixed simulation, and help Chinese chip design enterprises meet the challenges of mixed design and simulation. "

Zhou Zhenya, deputy general manager of R & D of BGI, said: "BGI has also found more and more requirements for simulation of mixed-mode design in marketing. This time, through the cooperation with Hejian Software on the digital-analog hybrid simulation scheme, the digital simulator UVS of Hejian Software and the circuit simulator ALPS of Jiutian are combined to create a set of national production and high performance digital-analog hybrid simulation scheme, which is believed to better meet the simulation verification requirements of more customers 'digital-analog hybrid design. At the same time, Huada Jiutian and Hejian Industrial Software have explored a path of collaborative innovation of domestic EDA product technology, which is believed to provide assistance to the development of China's EDA industry.
