Abstract: A method of avoiding substrate noise in an integrated circuit includes steps of receiving as input from an integrated circuit design at least a portion of a block for placement and routing on a substrate and an outer boundary of the block, selecting an end cell from a set of end cells for terminating the block in an outer area that extends from the outer boundary to an end cell boundary outside the block, and placing the selected end cell in the outer area to isolate the block electrically from the substrate.

Abstract translation: 避免集成电路中的衬底噪声的方法包括以下步骤：从集成电路设计接收块的至少一部分的输入，用于在衬底和块的外边界上放置和布线，从组中选择终端单元 的终端单元，用于在从外部边界延伸到块外的端单元边界的外部区域中终止块，并将所选择的端单元放置在外部区域中以将该块与基板电隔离。

An end cell is selected from a set of end cells for terminating the block in an outer area that extends from the outer boundary to an end cell boundary outside the block. The selected end cell is placed in the outer area to isolate the block electrically from the substrate.
