RE: [Ngspice-users] Ngspice can do digital simultaion?

[Ahmed Y. <Ahm...@xi...>]

Hi Al,
I am also interested in the two dissertations; yours and Karem's.
Is there any way I can get them?

Thanks...

Ahmed

Hi Al,

There is a similar simulator, xsim, which does multi-level
simulation. Its format seems to be the same as your gnucap. Do
you know what the difference between xsim and your gnucap is?

BTW, how can I get your Ph.D. dissertation? Could you mail
me a soft copy?

thanks,

Willis
