Abstract
The present invention involves a method for determining constant pins in a combinational circuit. The method comprises the steps of associating an input of a combinational circuit with a first variable and a second variable, wherein said second variable is the compliment of said first variable, computing for a first logical cell interconnected to said input a first canonical representation, wherein said first canonical representation is a function of the operation of said first logical cell and a function of said first value, computing for said first logical cell a second canonical representation, wherein said second canonical representation is a function of the operation of said first logical cell and a function of said second value, determining whether one of said first and second canonical representations is equal to zero.
