Abstract: A method of controlling an optimal cost is proposed, which can be applied to a circuitry designing process for making electronic products, allowing a user in drawing a circuitry to choose elements of identical specification with different unit prices, thereby achieving the objective of cost-optimization. The cost-optimization method comprises the steps of: first, integrating data of each of the elements of identical specification at different unit prices to form an element database; then, choosing each of the required elements for drawing the circuitry according to the data stored in the element database. The method provides an element database capable of storing and displaying electronic elements of identical specification with different unit prices for the users' selection, thereby achieving a primary objective of effectively controlling an optimal cost in circuitry designing.

Abstract: A method for managing net data of a layout is provided. The method comprises first establishing a net data classification index list in which a net name corresponds to a sub group; comparing a newly added net name with the net data classification index list; classifying the newly added net name to a designated sub group when the newly added net name does not exist in the net data classification index list; establishing an association between the newly added net name and the sub group; and storing the association corresponding to the net name and the sub group in the net data classification index list. Thus the efficiency for managing and utilizing the net data is improved.

Abstract: A method for quick naming graphics with the same properties comprises the following steps: selecting a plurality of graphics with the same properties from an operation window, then defining an object name and adding auxiliary symbols behind the object name by using the increment rule to generate a plurality of object names containing the sequentially corresponding auxiliary symbols; and marking the object names containing the respective auxiliary symbols on the respective graphics sequentially and correspondingly. Users may repeat the above steps to continuously select another object name, thereby achieving the quick naming of the graphics.
