Interactive P-cell Generation<\/h1>\n

1. Abstract<\/p>\n

Parameterized cells (P-cells) significantly increase the productivity of layout designers. Silvaco International\u2019s tool\u00a0Expert<\/em><\/strong>\u00a0has been designed to aid layout designers through its ability to support and manipulate P-cells based on its\u00a0LISA<\/em><\/strong>\u00a0script language. This simulation standard will demonstrate the capability of\u00a0Expert<\/strong><\/em>\u00a0and will identify its inherent benefits to the layout engineer.<\/p>\n

In previous versions of\u00a0Expert<\/strong><\/em>\u00a0layout editor new P-cells could be created only by direct input of the text of the\u00a0LISA<\/em><\/strong>\u00a0procedure that defines a p-cell, into the special P-cell panel (Figure 1). We shall call this approach \u201ctextual P-cell generation\u201d. To simplify writing of\u00a0LISA<\/strong><\/em>\u00a0scripts, it is possible to draw an instance of an intended P-cell in\u00a0Expert<\/em><\/strong>\u00a0editor, save it into XI-script format, and then edit the script manually to substitute the actual numeric values by parameters and formulas.<\/p>\n

While these approaches are acceptable for small P-cells, it becomes inconvenient with more complex P-cells and when large numbers of P-cells are required, e.g., by developers of cell libraries and PDKs.<\/p>\n

Therefore, \u201cinteractive parameterized cell generation\u201d is a new feature added into\u00a0Expert<\/strong><\/em>. This feature increases user\u2019s productivity of creating P-cells. It generates a parameterized cell with\u00a0LISA<\/em><\/strong>\u00a0xi-scripts from a geometric cell based on interactive functions \u201cStretch\u201d, \u201cRepetition\u201d, and \u201cLayer\u201d. After a P-cell is generated, parameter values can be modified to produce the desired cells.<\/p>\n

Rules for P-cell generation are applied to cell objects directly or via user defined control blocks. Several rules can be applied to one object \/block as well as one rule can be applied to several objects\/blocks. Control blocks can be of any shape (box, region, etc.).<\/p>\n

The \u201cStretch\u201d function is used to stretch or move selected objects in one of the following directions: left, right, up, down, left-up, left-down, right-up, right-down. Objects completely inside Control blocks will move, and partially overlapped by blocks will stretch.<\/p>\n

The \u201cRepetition\u201d function is used to repeat the selected objects in the specified direction with specified steps.<\/p>\n
