函数
L()
W()
vth() 阈值电压，pmos为正值
vdsat() 饱和电压即vgs-vth
rds() 电阻，不知是怎么来的
vgs()
cdo() dc drain current
gmo() gm operational 静态时gm
gdso() dc D-S conductance 导数为输出电阻gmo/gdso为直流增益

3, option 选项及VCVS VCCS param
若要导⼊到MATLAB中需要bin进制⽂件时需要设置好option并只使⽤.probe打印
.option post=1 //⼆进制
.probe tran V(out1) v(node1)
.option reltol
.option reltol=1e-5 abstol=1e-9
.option reli=XXX
.option methode=gear
.
option post=-0,1,2 // 打印科学进制和其它形式1,binary 2,ascii 3，减⼩⽂件空间⼤⼩。
.option post acct accurate // acct仿真结果写⼊ list ⽂件中。default=1, accurate仿真精度很⾼。.option node list post
.option GSHUNT=1e-11 CSHUNT=1e-11 method=gear
.option fast
.option ingold=2 //list中打印的数字为科学制度如10e8
