【摘要】：混合信號(hào)驗(yàn)證在當(dāng)前So C設(shè)計(jì)中的作用越來(lái)越重要,被稱(chēng)為芯片流片以前的健康體檢,可以有效避免芯片二次流片。結(jié)果證實(shí)大部分芯片的問(wèn)題可以通過(guò)合適的混合信號(hào)驗(yàn)證方法發(fā)現(xiàn)。當(dāng)前混合信號(hào)驗(yàn)證的主要挑戰(zhàn)包括行為級(jí)模型建模、晶體管級(jí)仿真速度、低功耗驗(yàn)證等,介紹了微控制器芯片KW41中使用的一整套混合信號(hào)驗(yàn)證方法,包括使用電路模型產(chǎn)生器生成wreal模型,混合模式數(shù)模混合信號(hào)仿真,模擬電路斷言和電路檢測(cè)幫助實(shí)現(xiàn)自動(dòng)化檢驗(yàn),模擬電路檢測(cè)發(fā)現(xiàn)模擬電路潛在問(wèn)題,用XPS MS做全芯片晶體管級(jí)仿真。該方法適用于所有數(shù)字設(shè)計(jì)為主的芯片。
[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.
