Abstract
A method for optimizing a circuit layout is provided which optimizes a circuit layout as a result of utilizing unused tracks of the circuit layout to expand supply lines. In a first step, a circuit layout is constructed by means of any circuit layout construction method, whereby requirements regarding the design of supply lines are reduced. Subsequently, in a second step, the method for optimizing a circuit layout is used.
Claims14
A method for optimizing a circuit layout containing a plurality of unused tracks and a plurality of supply lines, the method comprising:
- providing a set of requirements to be fulfilled by the circuit layout, the set of requirements defining a maximum voltage drop of the supply lines during operation of a circuit constructed according to the circuit layout;
- reducing the set of requirements with respect to the maximum voltage drop of the supply lines and with respect to a design of a section of the circuit layout concerning the supply lines and constructing the circuit layout in which the supply lines follow the reduced set of requirements;
- and
- optimizing the circuit layout by expanding the layout of the supply lines of the circuit layout using the unused tracks.
In a computer readable storage medium having stored therein instructions executable by a computer system for optimizing a circuit layout containing a plurality of unused tracks and a plurality of supply lines, the storage medium comprising instructions for:
- providing a set of requirements to be fulfilled by the circuit layout, the set of requirements defining a maximum voltage drop of the supply lines during operation of a circuit constructed according to the circuit layout;
- reducing the set of requirements with respect to the maximum voltage drop of the supply lines and with respect to a design of a section of the circuit layout concerning the supply lines and constructing the circuit layout in which the supply lines follow the reduced set of requirements;
- and
- optimizing the circuit layout by expanding the layout of the supply lines of the circuit layout using the unused tracks.
