This tip describes a way to dramatically speed up SpectreRF periodic noise sim's
while including real bias current noise. (The method also works with voltage noise, separate instructions are at the bottom of the message).To be accurate, SpectreRF noise
simulations should include the "real" bias current noise (as opposed to ideal
current sources). However, adding the real bias network (bandgap, bias current
distribution, etc.) to your sim schematic can cause SpectreRF to slow to a crawl
or even crash with insufficient memory, because of the increase in size and complexity of the test circuit.A way to overcome this limitation
while still using real bias noise is to use ideal current sources, while making
use of the "Noise File Name" parameter that is available on these sources. This
parameter causes the source to read a text noise file which is then included as
part of the noise simulation. Instructions follow for generating the text noise file.The easiest way to do this is to make a
separate sim schematic with just the bias network feeding into ideal sources as
loads. (Note, step-by-step instructions that follow refer to the 5.1.41 release of IC tools and AWD waveform environment.) One by one for each current value needed, do the following:
