The SoC system, SHU-MV08, reuses four new intellectual property （IP） cores and the design flow is accomplished with 0.35 btm chartered CMOS technology. Some special functions of IP cores, the detailed integration scheme of four IP cores, and the verification method of the entire SoC are presented. To settle the verification problems brought by analog IP cores, NanoSim based chip-level mixed-signal verification method is introduced. The verification time is greatly reduced and the first tape-out achieves success which proves the validity of our design.展开更多

Not only the data from AT 24C02C can be read automatically after power on, but also the data from upper computer can be written into AT24C02C immediately under the control of the IIC bus controller. When it is applied to blast wave overpressure test system, the IIC bus controller can read and store working parameters automatically. In a laboratory environment, the IP core simulation is carried out and the result is accurate. In the explosion field test, by analyzing the obtained valid data, it can be concluded that the designed IP core has good reliability.展开更多
