Digital emulation of an analog device with tolerance modeling

Abstract

A digital emulation of an analog device with tolerance modeling is disclosed. In operation, a model of an analog circuit is provided. The model includes the location of each individual element in the analog circuit. The model also includes a working value for each individual element as well as a tolerance range for each individual element. A randomized working value is then generated for one or more of each individual element based on the tolerance range and the working value. A digital emulation of the analog circuit is performed. The digital emulation uses the randomized working value for one or more of the each individual element and the working value for any remaining of each individual element. The digital emulation is then provided to a user for use in a digital environment.

What is claimed is: 
     
         1 . A digital emulation of an analog device with tolerance modeling comprising:
 a model of an analog circuit, the model comprising:
 a location of each individual element in said analog circuit; 
 a working value for each individual element; and 
 a tolerance range for each individual element; 
   a randomized working value generator to generate a randomized working value for one or more of each individual element based on the tolerance range and the working value;   a digital emulator to provide a digital emulation of the analog circuit, the digital emulator uses the randomized working value for one or more of said each individual element and the working value for any remaining of each individual element; and   a graphical user interface to present the digital emulation to a user for use in a digital environment.
