hspice波形问题

measurecharge INTEGRALI(vdd)FROM=0nsTO=50ns
.measureenergy param='charge*SUPPLY'
* ------------------------------------------------------------
*计算瞬态功耗*
*-------------------------------------------------------------
.printP(vdd)
* ------------------------------------------------------------
*计算平均功耗*
*-------------------------------------------------------------
.measurepwr AVGP(vdd)FROM=0nsTO=50ns
在波形中measure中的都显示不出来
敬请高手指点，小弟不胜感激！

.measure是在单独文件中显示的，不会再波形中显示
