Abstract :
We present a method for the automatic placement of substrate contacts by controlling their influence on circuit performance. This guarantees a layout that complies with the circuit´s specification concerning substrate coupling. The algorithm minimizes the substrate contact area. Our method can be applied at transistor and block level. An example at block level is presented.
