请问如何做LPE和PRE的步骤？

同求啊，顶起

同求啊

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
%>PDRACULA
:/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
LPEcomputes 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

有更详细的么?

提LPE有些参数要添写,如CAP,RES等
在文件的最后.

LOGLVS
cirnetlist
contopcell
x
PDRACULA
/grulefile
/f
jxrun.com
注意检查一下 outfile.lvs 文件，看看LVS都有没有通过。通过后再看输出文件（outputfile.DAT)文件

挺好。学习了

乖乖， dracula还有人用呢， LPE ， jxrun， 我在9年前学过，

那calibre 怎么做呢?谢谢
