Gdsii reference manual

GDSII Stream format is the standard file format for transfering/archiving 2D graphical design data. It contains a hiearchy of structures, each structure containing elements (boundary/polygon, path/polyline, text,box, structure references, structure array references). The GDSII Stream format manual says that a record may be infinitely long, but frankly, I don't see how it can get over bytes long, since the first two bytes of the record header are an unsigned integer that defines the length of the record. The leftmost bit of the first byte is valued at , the rightmost bit of the second byte is. Import: The GDSII import simulation object allows you to import structures from a GDSII file into the layout editor. The GDSII file format is commonly used to store 2-dimensional geometric data. This data can be directly imported into a 2D layout environment, or it can be used to import 3D objects into a 3D layout environment by extruding the 2D data in the Z dimension.

Command Reference File Export Mask Data L-Edit Online User Guide Contents Index Help File Export Mask Data Exports an existing layout data into a mask document. Both CIF and GDSII file types have additional export options. Clicking the Options button opens the Export CIF Options or Export GDSII Options dialog.

All shapes in the GDSII format are tagged with 2 properties: layer and datatype (or texttype in the case of www.doorway.ru). They are always 0 by default, but can be any integer in the range from 0 to These properties have no predefined meaning. It is up to the system using the GDSII file to chose with to do with those tags.

The GDSII file format is commonly used to store 2-dimensional geometric data. In this topic, we will walk you through the steps, format, and best practices for exporting your component design to a GDSII file. We will also show a simple but real GDSII example in silicon photonics. See also. Importing and exporting GDSII files.
