Accuracy of magnitude-class calculations in switch-level modeling

The relationship between switch-level circuit models and the linear electric circuits from which they are abstracted is investigated. This is important in determining the accuracy and consistency of switch-level simulation programs. A precise definition of magnitude or strength classes is presented, which leads to exact bounds on the accuracy of resistance and voltage calculations with magnitude classes relative to the corresponding linear calculations. The results indicate that the potential of switch-level simulators to provide accurate results is far less than was previously thought
