求助:如何做dracula的SVS(schemitic versus schemitic)

没用过dracula，为什么不直接导网表对比

SVS Overview
Schematic Versus Schematic (SVS) compares two schematics. The two schematics must be
in different directories. SVS requires the following commands in the Description block:

SVS-LAYOUT specifies the layout data file generated by LOGLVS.

SVS-SCHEMATIC specifies the schematic data file generated by LOGLVS.

HCELL-COLUMN-1 specifies whether the first column in the Hcell table lists layout or
schematic cells. This command is required for hierarchical Dracula only.
For more information about these commands, refer to Chapter 10, “Description Block
Commands.”
Running SVS in Flat Mode
The following is an example of a rules file for flat mode SVS:
*DESCRIPTION
PRINTFILE = lvsprt
PROGRAM-DIR = /DRACULA/
SVS-SCHEMATIC = LVSLOGIC.DAT
SVS-LAYOUT = ../LVSLOGIC.DAT
*END
;
*OPERATION
LVSCHK
*END

先將兩個netlist做loglvs
會產生兩個LVSLOGICDAT
SVS command file 修改如下
*DESCRIPTION
PRINTFILE = lvsprt
PROGRAM-DIR = /DRACULA/
SVS-SCHEMATIC = LVSLOGIC.DAT
SVS-LAYOUT = ../LVSLOGIC.DAT
*END
;
*OPERATION
LVSCHK
*END

Running SVS in Cell or Composite Mode
Here is an example of a rules file for cell or composite mode SVS:
*DESCRIPTION
PRINTFILE = lvsprt
SVS-SCHEMATIC = LVSLOGIC.DAT
SVS-LAYOUT = ../LVSLOGIC.DAT
program-dir = /DRACULA/
CHECK-MODE=comp
HCELL-FILE=../cell.tab
*END
;
*OPERATION
LVSCHK
*END
