Retain Layout Information in the Abstract View
Abstract Generator allows you to save layout details along with the pin shapes and blockages in the final abstract generated. To retain the layout information, you can use the AbstractRetainLayout option of the absAbstract SKILL command.
absSetBinOption(“Block” “AbstractRetainLayout” “true”)
By default, the AbstractRetainLayout option is set to false, so the final abstract contains the adjusted pin shapes, blockages, and boundary based on the options specified. All other shapes or data in the layout cell-view is deleted.
To include the layout information in the abstracts, set the AbstractRetainLayout option to true. The layout information along with the pin shapes and blockages will be written to the abstract view. You can change the name of the abstract view in the Views Tab of the General options dialog box (File – General options) by specifying the name in the Abstract view name field.
Alternatively, you can use the absSetOption SKILL command line to change the abstract view name.
absSetOption(“ViewAbstract” “layout.pin”)
You can use the AbstractRetainLayout option to create pins in your layouts so that they can be used in the Virtuoso® XL layout editor environment. If you do not want blockages in these layouts, do not specify any layers in the Layer Assignment for Blockages table on the Blockage tab of the Abstract step.
