求翻译：电路采用SMIC0.18umCMOS工艺实现，用cadence软件进行仿真验证。设计并验证了带隙基准电压源等关键模块，通过拟计算、仿真、扫描，最终确定参数取值。仿真结果表明芯片可以实现预先设定的各项功能及性能指标。是什么意思？

The circuit smic0.18umcmos process simulation cadence software. Design and verify the key modules of the bandgap reference voltage source, intended calculation, simulation, scanning, and ultimately determine the parameter values. The simulation results show that the chip can be pre-set the function
