Re: [Ngspice-users] laplace

[Dietmar W. <die...@ar...>]

But Stuart, you know it better, following text is running in ngspice with the xspice extension 
you have implemented years ago:

Laplace Test
***
A1 1 2 laplace1
***
v1 1 0 DC PWL(0 0 0.3 1.0 10 1.0) 
R1 2 0 1k
***
***F(s)=1/(s^2+1.01*s+1)
.model laplace1 s_xfer (in_offset=0.0 gain=1.0 num_coeff=[1.0] 
+ den_coeff=[1.0 1.01 1.0] int_ic=[0.0 0.0] 
+ denormalized_freq=1)
***
.tran .1s 10s
.end

Hugo - look in the xspice examples to s_xfer.
