High-level languages such as C＋＋/SystemC can play multiple roles in system design as target languages. There are many practical problems in the application of object-oriented methods for this goal. Based on the analysis of traditional and system-level design methodology, a new object-oriented SOC design methodology with object-oriented design patterns is proposed, which emphasizes high-level design and verification. Aiming at the final goal of developing design patterns specific to SOC design, the reuse of design patterns in SOC systems and the capability of new SOC design patterns are discussed. With the illustration of some concrete examples of SOC design patterns, the application of object-oriented design methodology in the SOC design process is presented.展开更多

Using the ANSYS finite element analysis, the temperature distribution of the chip is simulated and analyzed.The optimal size of the chip is 30×22 mm2, the roundabout micro-channel is the 90 μm width, 40 μm depth. Two micro-heater with the nickel-chrome alloy material film are formed on the side of silicon belonging to denaturation and renaturation zones needed for PCR reaction, and two adiabatic structures with groove on side of silicon by anisotropy etching. By the mode of heating local zones at single side, three wider constant temperature zones could be formed, which are 60 ℃,72 ℃,95 ℃ and suitable for PCR,and the temperature-difference could be restricted in less than 5 ℃.展开更多
