ABSTRACT:
One aspect of the invention relates to a method for computer aided optimization of a cost of an electronic circuit, the cost being a function of a plurality of circuit parameters. In one embodiment, the method involves the steps of selecting an initial vertice, the vertice being defined by specific values of the circuit parameters; determining a number of additional vertices required; selecting a plurality of additional vertices which, along with the initial vertice, define a region; simulating the circuit to determine individual costs associated with individual vertices; comparing the individual costs with one another to determine a worst cost; determining a centroid defined by the vertices, excluding the vertice associated with the worst cost; determining a new vertice, the new vertice being located on a line defined by the vertice associated with the worst cost and the centroid, the new vertice being located at a distance away from the centroid, the distance being proportional to a distance factor; simulating the new vertice to determine the associated cost; and comparing a cost associated with the new vertice to a termination criteria.
