Random signal generation for PSPICE/SPICE

The SPICE programs we use for circuit simulation do not have a direct way to generate random waveforms. i.e. there is no voltage or current source which can be attached to a circuit node and which can generate a random signal for analysis. As a result we had to develop code on MATLAB and C++ to allow us to generate a PWL random waveform of as long a length as required. It is used as a piece wise linear signal and can generate the random signal as required.Please contact us through our website located at http://www.signalpro.biz for more information about this circuit simulation tool.
