[Ngspice-devel] XSPICE noise support

[Seth H. <se...@ki...>]

Hi Holger, et al

There was a line in noisean.c that said "/* MIF_NOI is not yet supported by
code models, so use their AC capabilities */"

Based on offline discussion, this is required to fully implement the
LTSPICE OTA model, which some manufacturers use in their provided models.

The attached patch implements this.  It provides standard noise parameters
for simple declarative models and a programmatic interface for code models
to define their noise sources.

Let me know if this is acceptable or if you'd like changes.

Seth
