Description |
|
ASM 2600 enables engineers to create precision masks directly on a pattern generator from drawing data in GDSII stream format. A variety of hybrid and IC design software can output GDSII stream.

A typical hybrid layer to be fractured. Includes all angle data. Uses re-entrant polygons to create the solder dams. |
 The metal layer fractured by ASM 2600. These flashes are sent to the PG machine which exposes a glass plate. Program ModulesGDS2IReads in the GDSII stream file and fractures each boundary into rectangular flashes. Supports GDSII path types 0 & 2. The user can specify a list of layers to fracture. Converts GDSII text into flashes using built in PG font. Outputs Intermediate (.int) binary file.
EMASKThe EMASK module takes output from GDS2I and creates Electromask 2000 format PG code. Includes functions for arraying data, oversizing flashes, offsetting data and scaling. Can combine several different intermediate files into a single PG file.
MMASKTakes output from GDS2I and creates David Mann 3000 or 3600 PG code. Same functions as EMASK.
PG2GDSConverts Pattern Generator code back to GDSII stream format. Each flash is converted into a GDSII boundary of the appropriate width, length, and rotation.
