    Co-design technology of soc based on active-HDL 6.2
    (EWDTW, 2004) Hyduke, S.; Yegorov, A. A.; Guz, O. A.; Hahanova, I. V.
    It is represented technology of designing and verification of digital systems-on-a-chip (SoC), based on the experience of design of hardware and software components of SoC in one environment. It reflects today situation of variety of available silicon, software and hardware description languages, design tools. There are also presented recommendations and examples. On today’s EDA market there are 3 major target silicon technologies that define computer world today – programmable devices, gate arrays and ASICs. They and relations between them are presented on Fig. 1. That includes manufacturing technology of silicon chips, hardware and software description languages, design tools, SoC methodology. ASIC GA PLD ASIC + PLD CPU+PLD ASIC+CPU+PLD 90 Nm-technology ASIC +CPU Design tools based on HDL SOCs based on: Fig. 1. Cause-effect relation on the EDA market Practical explanation of presented figure is that because of influence of SoC on ASIC and FPGA (PLD) designs it is started integration between them. On FPGA’s started to appear powerful embedded processors such as ARM and PowerPC. For example latest Xilinx Virtex II Pro FPGA is 4 embedded IBM PowerPC processors plus 10 million of programmable gates available for user. Design flows of FPGAs and ASICS also started to merge after announcing by Altera Structured ASIC flow. Where FPGA verified design is transferred to ASIC without any participation of the developer. That will influence world chip market – that is about $40 billions per year: 1) powerful processors, that are used on servers and working stations; 2) personal computers area, where Intel processors holding the leading place with $20 billions; 3) microcontrollers and signal processes generate to vendors $14 billion revenue every year. The 3rd segment is the most growing one from all three. Hardware development reached stage that number of transistors is growth is 60% per year, but their usage in project growing only 20% per year. That’s why we can see today rapid growth of number of SoCs. On that available space on a chip are transferred from the board all buses and peripherals of the developed system. That allows not only increasing productivity of whole digital system and make it with custom functionality, but significantly to reduce energy consumption and decrease physical size of final product. At the same time one of the main requirements of designing complex systems today is to use module approach. Where designer can reuse modules from previous projects or use IP(Intellectual Property)-core. For SoCs there are bunch of various ready to use processors with peripheral buses and libraries of standard peripherals. With different functionality, sizes, from simple interface to complicated 64bit processors that requires couple of millions transistors.
