Abstract
A method for providing a mathematical expression in the form of a posynomial or max-monomial function for a performance metric of an integrated circuit is disclosed. Data representing a plurality of circuit variables is provided and curve fitting occurs to selected ones of the variables. A plurality of expressions may be used and when used, error at the transition from one expression to another is checked. The resultant expressions lend themselves to a global solution with design problems expressed as geometric programs.
Claims6
A method for representing the operation of an integrated circuit as a posynomial or max-monomial expression comprising:
- providing data for a plurality of design variables for the operation of at least one performance metric for the integrated circuit;
- selecting from the plurality of variables at least one variable which influences the performance metric;
- fitting a posynomial or max-monomial function to at least a part of the data containing the selected variables;
- and
- checking error occurring between the data and the function.
