最近一直在研究如何做lib，有个问题很困扰，有人用过ncx这个工具吗，
在启动ncx的时候，我设置的主要控制语句如下，
##template options
set input_template_dir config
set template_suffix .opt
set precision 5
set farm_type noFarm
##timing model options
set timing true
set ccs_timing false
set compact_timing false
set nldm true
##power model
set ccs_power false （不想让他生成ccs模型）
set compact_power false
set power true
set nlpm true
set variation_leakage true
我不想让他生成ccs power的东西，可是我即使这样设置了，工具竟然还是认为我用了ccs power，log文件有以下信息：
Timing model acquisition options:
ccs_timing : false (user)
compact_timing : false
nldm : true (user)
capacitance : true
delay : true
constraint : true
shpr_constraint : false
design_rules : false
max_capacitance : true
max_transition : true
variation : false
mismatch : false
Power model acquisition options:
ccs_power : true (user)（ 我设置的明明是false，工具竟然认为是我设置了true）
compact_power : false (user)
nlpm : true (user)
variation_leakage : true (user)
为什么工具会把false认为是true呢，我很不解啊，这样导致我做出来的lib是下面的样子：

cell_leakage_power : 6.275513e+01;

。。。。后面还有很长一大串CCS的东西，前面的算正常的，我怎么设置才能不让他弄出这些CCS的东西呢，东西出来呢？高手帮忙解决下我这个困惑吧 |
