Import Oasis Form

Use the Import Oasis form to create cellviews from existing layout information in OASIS format.

Field Description

Oasis Filenames

Specifies the names of the OASIS files that you want to import. Use the Browse button to help you locate the files.

Map Oasis names

Lets you specify whether you want OASIS names mapped to uppercase, lowercase, or not to be mapped at all.

Layer Map Table

Specifies the name of the layer map file you want to import. Use the Browse button to help you locate the file.

Default Bin

Lets you select the bin into which the cells are imported. This option applies only to any new library cells being imported. Cells imported previously are not moved.

During import, Abstract Generator creates layout views for the cells in the library. Some types of cells, such as sites and generated vias, do not need to be processed, so Abstract Generator moves them directly into the Ignore bin. A cell is placed in the Default Bin only if it meets the criteria below.

  • There is a valid layout view.
  • The cell is not a via.
  • The cell is not a site.

Template Filename

Specifies a stream template file to be imported into Abstract Generator. Use the Browse button to help you locate template files.

If you do not select a template file, Abstract Generator creates a default file called PcsStreamIn.template in the .abstract/import directory. This file has default option settings of No Mapping and Core bin and can be used to create your own template file.

Regardless of whether a template is supplied or not, the values of the Oasis Filenames and the Map Oasis names options are always the values specified in the form.

Technology Reference Library Name

Allows you to specify one or more valid reference technology libraries in the Technology reference library name field. The specified referenced technology libraries must be present in the cds.lib file and must be readable.
