Abstract
An integrated circuit design tool apparatus including a processing resource arranged to support a circuit simulator, a circuit simulator interrogator, and a well distance calculator is provided. The circuit simulator interrogator communicates first and second well distance values separately to the circuit simulator and receives first and second performance parameter value back from the circuit simulator interrogator in response. The well distance calculator determines a performance parameter limit value, and projects, substantially linearly, a well distance change value in respect of the performance parameter limit value using the first and second performance parameter values, the performance parameter limit value and a trial well distance change value. Also, a well distance change characterizing equation using the well distance change value projected is used in order to obtain the minimum well distance value associated with the performance parameter limit value.
