类型13：
在多电源中，器件连接到不正确的电源。
图例表示source端连接电源不对应。
类型14：
当LVSCHK[K]选项(保持并联)没有打开，并联的MOS晶体管将会合并为一个MOS晶体管，其余的MOS晶体管将不会被检查到或作为错误标识出来。(些类型不作为错误来解释)
图例表示并联器件合并为一个器件。
类型15：
当LVSCHK[F]选项(CMOS gate过滤器)打开，没有被使用的CMOS器件将被过滤。(此类型不作为错误来解释)
本篇完
以后会对LVSCHK及Option作详细的介绍，敬请关注。
calibre中LVS问题
wawejin 发表于: 2009-9-08 22:30 来源: 半导体技术天地 calibre进行LVS时 出现问题其lvs report部分如下： Error: Different numbers of ports (see below). Error: Different numbers of nets (see below). Error: Different numbers of instances (see below).
Error: Connectivity errors.
Error: Instances of different types or subtypes were matched.
Error: Cells with non-floating extra pins. Warning: Unbalanced smashed mosfets were matched.
