【摘要】：混合信号验证在当前So C设计中的作用越来越重要,被称为芯片流片以前的健康体检,可以有效避免芯片二次流片。结果证实大部分芯片的问题可以通过合适的混合信号验证方法发现。当前混合信号验证的主要挑战包括行为级模型建模、晶体管级仿真速度、低功耗验证等,介绍了微控制器芯片KW41中使用的一整套混合信号验证方法,包括使用电路模型产生器生成wreal模型,混合模式数模混合信号仿真,模拟电路断言和电路检测帮助实现自动化检验,模拟电路检测发现模拟电路潜在问题,用XPS MS做全芯片晶体管级仿真。该方法适用于所有数字设计为主的芯片。
[Abstract]:Mixed signal verification plays a more and more important role in the current so C design. It is called the physical examination before the chip flow sheet, which can effectively avoid the secondary flow chip.The results show that most of the chip problems can be detected by a suitable mixed signal verification method.At present, the main challenges of mixed signal verification include behavioral model modeling, transistor-level simulation speed, low-power verification and so on. This paper introduces a set of mixed signal verification methods used in microcontroller chip KW41.Including the use of circuit model generator to generate wreal model, mixed mode digital-analog mixed signal simulation, analog circuit assertion and circuit detection to help achieve automatic testing, analog circuit detection found potential problems in analog circuits,XPS MS is used to simulate the whole chip transistor level.This method is suitable for all digital design chips.
