Abstract
A method is disclosed for storing and reusing the PC description of layout cells. A database stores predefined cells and PC descriptions that were previously calculated by a 3D field solver. Regarding a candidate cell from the layout diagram, the database is searched for a substantial match amongst the predefined cells. If there is a match, then the stored PC description of the matching predefined cell is assigned to the candidate cell in the layout diagram, which avoids having to make a discrete calculation for the PC description. If there is no match, then the 3D field solver is applied to the candidate cell in order to calculate the PC description of the candidate cell. To facilitate reusing the newly calculated PC description, the candidate cell and the newly calculated PC description are stored in the database as a new predefined cell and its corresponding PC description.
