Patent ID: 8712751

Claim:
A system comprising: a computer, wherein the computer simulates: a first digital function module that represents a first analog circuit; a second digital function module that represents a second analog circuit, wherein the second digital function module receives a first value representing a first analog signal from the first digital function module and transmits a second value representing a second analog signal to the first digital function module, and wherein the first analog signal from the first digital function module is a current signal related to a first output signal of the first analog circuit and the second analog signal from the second digital function module is a voltage signal related to a second output signal of the second analog circuit; and a single bi-directional connection between the first digital function module and the second digital function module that represents a bi-directional connector coupled to an output of the first analog circuit and to an output of the second analog circuit, wherein the single bi-directional connection communicates the first value from the first digital function module to the second digital function module and communicates the second value from the second digital function module to the first digital function module.
