真厉害 |
xunjh 发表于 2012-8-10 20:17 好厉害啊,我刚刚学sigrity不久,请问一下调用.s2p的模型,为什么用写.ckt 的东西,ckt是干什么用的,我看到sigrity自带的库里面 有.s2p的模型,我需要怎么正确的调用呢? 求指教# o. }# E6 h0 W' g0 ^, W: T4 |( k4 j |
学习了,谢谢 |
自己解答一下吧,可以通过broadband spice将sNp档转换为宽带spice模型(.txt),然后在.ckt文件中调用subckt中定义的即可,如下所示: .subckt bla31ag102sn4 1 2 ref - M0 a0 h' k$ T, `9 h Rd1_1 3 ref 50.000000 Rd1_2 4 ref 3.535534 Vd1 1 3 0 F1 ref 4 Vd1 1.0 G1 ref 4 1 ref 0.02 Rd2_1 5 ref 50.0000001 D* ?2 g$ _' N W Rd2_2 6 ref 3.535534 Vd2 2 5 0 F2 ref 6 Vd2 1.0 G2 ref 6 2 ref 0.02, f* Y8 d$ i( N% b G3 ref 3 LAPLACE 4 ref: k; Y' `% t.

是不是不能通过.ckt文件调用S参数文件呢,如果用HSPICE的.sp文件,应该写成什么样子? |
