The spice description as follows:
.lib “ls35_4_1.l” tt
.option post probe
.param Cload =10p
.param Tpw=opt1(0, 0, 15n)
.model optmod opt method=passfail
.tran 0.1n 20n sweep optimize=opt1
+ result = Tprop
+ model = optmod
.measure Tran Tprop Trig V(in) Val=2.5 Rise = 1
+ Targ v(out) Val=2.5 Fall = 1
vcc 1 0 5
vin in 0 pulse(0 5 1n 1n 1n Tpw 20n)
....
.end
I read this optimization example with hspice in a book,but I cann't understand it.Who can tell me ???
Thanks!!
