in the case of the version i sent you, which was created from using
nsxlib, those will be part of alliance-check-toolkit, but you will
have to convert
those from their VHDL source code.

no because they'd be auto-generated output, from nsxlib and niolib.


there is almost certainly a way to write a python script which
will perform the required auto-generation to read in the
vbe and output spice: i just don't know (personally) what that is.

we had very little time in which to get a hell of a lot done, and
not a lot of additional help to do it.  therefore the spice output mode
was added by Jean-Paul extremely quickly with only something mad
like two weeks remaining to the July tape-out deadline.

as best i recall: pre- and post- place-and-route.
