>> [Ngspice-users] Noise analysis depends on ac parameter
The noise analysis internally depends on an ac analysis
to derive "inoise" from "onoise"
("onoise" is multiplied with the inverse ac gain from input to output)
This AC analysis used all the given ac magnitudes for all vsrc/isrc
devices in the deck.
This fix overrides all ac magnitudes with zero,
except for the given input device,
whose magnitude is set to one.

This comes in two flavours,
1) an empty circuit
2) a xspice circuit with exclusively xspice event nodes
In the B language this can be considered a bug fix.
In the .control language this is a severe change
and breaks backwards compatibility.
In all three languages 'numparam' 'B' and '.control' we now have
ln to the base e
log to the base e
log10 to the base 10
Thus log and log10 is now consistent
with the vast majority of programming languages.
ln is merely for convenience.
very few other languages have it.
I'd like to discourage its usage.
