1.要有LPE或PRE文件,此文件类似于dracula的LVS文件
2.要做通LVS,ERC检查
3.跑LPE或PRE
%>DRACULA
:/get *.pre(*.lpe)
:/f
%>jxrun.com

hi lyh88011,

you should create LPE/PRE command files at begin, then run the PDRACULA procedure and jxrun.com.Below are some basic concept of DRACULA LPE/PRE,just for your reference
LPE  computes and extracts the following key electrical parameters from IC layouts
   Fixed capacitance of nodes
  Areas and perimeters of diodes
  Gate size of transistors
  Areas and perimeters of bipolar transistors
  Beta ratios

And PRE enhances LPE by extracting parasitic resistance created by any of the conduction layers in the layout
