为此,将layout netlist的电路与schematic netlist网表进行比较,称为Layout versus Schematic(LVS)。 我以前用的比较多的跑DRC和LVS的工具是Calibre. 图1 Layout和Schematic示意图 一般LVS的输入件如下: GDS(layout stream file):LVS工具通过GDS提取生成layoutnetlist,用于LVS比较。 Schematic netlist:用作 LVS 比较的sou...
LVS - not compared, number of port 0 in layout Hello, so after making layouts, when I try to run DRC and LVS chceks, DRC runs successfully without any errors, but when i try to run LVS for the same layout, it shows an error which says "not compared" and the number of ports are...
Layout Versus Schematic (LVS) checking compares the extracted netlist from the layout to the original schematic netlist to determine if they match. The comparison check is considered clean if all the devices and nets of the schematic match the devices an
LVS check (i.e., the number of fingers property is dropped during the reduction process, and the source and drain diffusion information is missing in the extraction process). Since the inventive method treats a multi-finger FET as one entity, it extracts as many properties as defined in the...
Re: Regarding DRC/LVS? santhosh.mandugula said: Hi everyone, While doing DRC/LVS if you get an error message as “noting in layout “ , what can be the possible reason of error ? this must be an error in LVS only and not in DRC. there must be some devices in the schematic tha...

Port swap errors Open 具有相同layout text的net的shapes不相交或不接触导致设计中有open(开路).。Opens 意味着设计中有floating connections.Floating connection会导致芯片的重大缺陷。所以发现和找到design中的open非常重要。在进入LVS环节前,在PnR工具中进行相关检查很有帮助。
