To overcome the challenges brought by the scale down of feature size, a flow of physical design and verification for embedded CPU under deep submicron technology is put forward in this paper. New problems are encountered in timing closure, signal integrity, IR drop and antenna effect, so we must select the effective EDA tools and develop new flow of physical design and verification combining with the characteristics of circuit under deep submicron technology. New challenges are analyzed, especially the interconnect line effect, and how to prevent the crosstalk and ensure the timing performance has been discussed. The embedded CPU CK610 using 0.13um 1P4M CMOS process technology has been completed by this new flow and the result indicates this chip complies with all requirements.

Extended-Range Electric Vehicle (E-REV) is one of the most feasible transitions from fossil-powered cars to pure electric vehicles, since the technologies of battery need further development. A possible solution of E-REV is introduced in this passage, which also provides methods of designing and selection of key components in the powertrain system. The design is based on the performance requirements, including driving motor, battery system and range extender.

LED lighting becomes the forth generation green lighting. However, in terms of LED development and large-scale application, the reliability of LED has become one of the technical bottlenecks. This paper carried out the research on the thermal-humidity reliability of high power LED module by the means of experiment and simulation, which mainly aims at the reliability problems existed in high power LED products. Thermal-humidity experiments which takes high power LED module with 10W as the experimental sample and simulation analysis based on FEM (Finite Element Method) software ANSYS are carried out. The results show that, high temperature is the main factor which affects the thermal-humidity reliability of high power LED module.
