一、常规网表

Inverter

.lib "D:\lib\l0040ll_v1p4_1r.lib" TT

.param SUPPLY=.1V

.param T=10ns

.param dt=.02ns

.temp

.global VDD VSS

.option MEASDGT= post    *MEASDGT=3表示输出结果保留3位有效数字

VVDD VDD  'SUPPLY'

*测量语句

.Measure tran pwr AVG P(VVDD) From=0ns To="3*T-dt"

.Measure tran Tr trig V(out) val='0.1*SUPPLY' rise=

+                targ V(out) val='0.9*SUPPLY' rise=

*瞬态扫描语句

.tran .001n "6*T"

*.print tran V(in) V(out)

.probe v(*)

二、直流分析网表

HSPICE demo

.LIB ".\cmos25_level49.lib" TT

.temp

.plot DC I(M0)

VVSS VSS

VVDS D VSS

VVGS G VSS 0.5

.dc VVDS   0.1 sweep VVGS 0.5 2.5 0.5

M0 D G VSS VSS nmos L=.5u W=.8u

.end

　　打开生成的.sw0文件可以看到如下的波形：
