找到了,在LVS规则文件开始的NOTICE 里面,第五条就是改精度的说明。默认MOS管的精度是0%,就是一点误差不能有!
NOTICE: (Read Me First!)
1) The runset is tested and developed on Calibre version v2007.3_36.25,
please use this or newer version of Calibre to execute this rulefile.
2) It's recommended to run hierarchical calibre lvs as false error might be
occur with flat mode.
3) Format of calibre text file is as follows:
LAYOUT TEXT "text string" [x] [y] (layer num) (cell name)
4) Default property resolution for ambiguity is 32.It is necessary to increase
this value to resolve serious ambiguity. Uncomment statement 'LVS PROPERTY
RESOLUTION MAXIMUM' in this deck to reset the capability of property resolution.
5) Default MOS property tolerance is 0%, Resistor property tolerance is 1%,
Capcitor property tolerance is 1%, Diode property tolerance is 1%, BJT
property tolerance is 1%. If specific property tolerance is needed,
please modify following commands.
VARIABLE PROP_TOL_M 0 --> MOS
VARIABLE PROP_TOL_R 1 --> Resistor
VARIABLE PROP_TOL_C 1 --> Capacitor
VARIABLE PROP_TOL_D 1 --> Diode
VARIABLE PROP_TOL_B 1 --> BJT |
