Re: [Ngspice-devel] "new_kirchhoff" KCL Verification?

[Ryan F. <rya...@up...>]

Hi Francesco,
Thanks for the details. I'm not worried about it right now, but I just
wanted to make sure I could plan for it in the future.  I am excited to
hear that the approach used in SPECTRE is in works though! :)
