Patent ID: 7703050

Claim:
A method, comprising: generating an optimization problem in standard form whose constraints are based on equations that describe aspects of an electronic circuit's operation, said constraints including: (i) a first function that varies linearly with a first design variable of said circuit; (ii) a second function that is posynomial with an e kx term where k is treated as a constant and x is said first design variable, said e kx term being an approximation of and replacing a term found in said second function when said second function is articulated as a standard form expression of an aspect of said circuit's operation without said approximation; (iii) a posynomial function, said posynomial function being a result of a transformation of another function that, when articulated as a standard form expression of another aspect of said circuit's operation, is a signomial function having negative coefficients; finding a solution to said optimization problem by processing software program code with a computing system; incorporating said solution into a computer readable design of said circuit.
