Is there any source (voltage, preferably) which can be specified as a noise-source and whose frequency characteristics can be defined. I am actually trying to find a replacement for Noise Function in Eldo. In it, one can defince a voltage source with a noise function which takes 3-8 parameters - Thermal Noise floor, Flicker Noise level at 1Hz, slope for flicker-noise and few more parameters.

Hi,
I tried to solve my problem by using vsource with spot noise defined
at few noise-frequencies but the problem is that it does linear
interpolation while I need logarithmic interpolation for my purposes.
Is it somehow possible?

You could write a verilog-a model which uses the white_noise,
flicker_noise functions, for example.

Andrew.
