Abstract:
1. A machine implemented method of simulating a design of an electronic circuit comprising: simulating the design by analyzing the design of the electronic circuit by identifying one or more process parameters of the electronic circuit and at least one process variation for at least one of the one or more process parameters; determining a numeric value for a characteristic of at least one of a plurality of components of the electronic circuit, in which the characteristic comprises a nominal part and a variation part and the value is expressed as a polynomial function of the at least one process variation for the at least one of the one or more process parameters, wherein at least a part of the polynomial function is analytically determined, wherein the characteristic identifies a process condition of or a physical, an electrical, or a performance attribute of the at least one of a plurality of components; reducing the variation part of the component value by compression to produce a compressed variation part by pruning or removing a hyperplane, wherein the hyperplane identifies a condition for the electronic circuit with respect to the characteristic; and displaying a result of the reduction the variation part or storing the results in a tangible computer readable medium.
