Abstract:
A method for assigning thin-oxide and thick-oxide capacitors on an integrated circuit, the integrated circuit having a capacitance requirement and an available capacitance area, the method comprising:determining a first amount of capacitance assuming that the available capacitance area is filled with said thin-oxide capacitors; determining a second amount of capacitance assuming that the available capacitance area is filled with said thick-oxide capacitors; defining a capacitance range as a range between the first amount of capacitance and the second amount of capacitance; determining if the capacitance requirement is within the capacitance range; and if the capacitance requirement is within the capacitance range, assigning said thin-oxide capacitors to a first percentage of the available capacitance area, and assigning said thick-oxide capacitors to a second percentage of the available capacitance area in order to substantially achieve the capacitance requirement and substantially minimize leakage power attributable to the assigned thin-oxide capacitors and thick-oxide capacitors.
