Automated Design for Micromachining



This parameterized cell draws a cross. This may be useful, for example, for drawing alignment marks.

Layout for a cross.

Any parameter may be modified, if necessary, to meet design rules. Typically, this involves increasing parameters that specify distances, so that minimum line width and minimum line spacing rules will not be violated. This has been extended to the convention of specifying a zero for some parameters to obtain an instance of the minimum size.

In addition to the parameters listed below, several technology parameters also influence the implementation of parameterized cells. This data must be present in the technology library.

Table 1: Parameters for the 'cross' parameterized cell.
Name Description Range Units
layer This must be one of the drawing layers in the technology, and specifies the layer onto which the circle will be drawn. dwg layers -
size This parameter determines the width of the arms, as well as their length. [0,∞) um
