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
