The Goodson series CPU design is comprised of 32-bit integer and 64-bit floating point functions with performance of 200MIPS at up to 266MHz clock frequency. Since its functionality is complicated, complete functional verification for such chips can require several months. The VStationPRO emulator provides RTL or gate-level verification for designs up to 120 million gates and is widely used for the functional verification of complex system designs such as CPUs, image processors and multi-media/communications system-on-chips (SoCs).
"With the great help of Mentor's advanced VStationPRO verification system, ICT will be able to slash verification time and supply its customers with fully verified Goodson CPUs in a short time period, which will accelerate its adoption," said Mr. Tang Zhimin, the technical principal of the Goodson chip project at the Institute of Computing Technology of the Chinese Academy of Sciences.
The VStationPRO emulator is the Mentor Emulation Division's sixth-generation VStation product family and provides the high performance and capacity required for such applications as hardware/software co-verification, accelerated verification, direct code verification and in-circuit emulation (ICE). Complex system design verification can be greatly shortened while ensuring highest function coverage with the VStation solution, with emulation speed thousands of times faster than other methodologies. The VStation system was used to reduce verification time for the Goodson CPU design.
"ICT selected the VStationPRO emulator as its Goodson series CPU functional verification platform because of Mentor's advanced technology and excellent support," said Danny Perng, general manager, Mentor Graphics China. "We are pleased that our most advanced emulation platform will contribute to the success of the Goodson series chip design and verification flow."
The Institute of Computing Technology of the Chinese Academy of
Founded in 1956, the Institute of Computing Technology of the Chinese Academy of Sciences (ICT-CAS) is the first academic institution specializing in the comprehensive research of computer science and technology. China's first general-purpose digital electronic computer was created at ICT-CAS, which later became a research and development base for high-performance computers. It is also the birthplace of the first high-performance general-purpose CPU chip.
At present, there are six research labs, one engineering center, and several incubated high-tech companies at ICT-CAS, hence, forming a well-coordinated system of scientific research and commercialization. The major research areas at ICT-CAS are CPU and SoC design, high-performance computing and grid computing, network and digitalization technologies, information processing, and intellectualized Internet software.

About the Goodson Chip Central Processing Unit (CPU)
The "Goodson Chip No. 1" is the first commercial general-purpose CPU chip designed independently by China with self-owned intellectual property rights. The CPU has 32-bit integer unit and 64-bit double precision floating point unit that meet the IEEE754 standard. "Goodson Chip No. 1" is designed and manufactured with 0.18um technology, with up to 266MHz maximum clock frequency and top calculation speeds for both integer and floating point exceeding 200MOPS. The chip has passed high/low temperature loop test and reaches industrial application standards. With respect to operating system (OS) software, the Goodson Chip also supports popular international operating systems such as Linux, VxWorks and China's "Hopen (Creation Goddess of China)" embedded OS, making the Goodson Chip suitable for embedded system applications.
