Besides the commercial vendors there are plenty of free GDSII utilities. GDSII utilities Īs the GDSII stream format is a de facto standard, it is supported by nearly all EDA software. ![]() While these attributes were designed to correspond to the "layers of material" used in manufacturing an integrated circuit, their meaning rapidly became more abstract to reflect the way that the physical layout is designed.Īs of August 2022, many EDA software vendors have moved to the better stream format, OASIS, which replaced GDSII. Objects contained in a GDSII file are grouped by assigning numeric attributes to them including a "layer number", "datatype" or "texttype". GDSII files were originally written on magnetic tape. GDSII files are usually the final output product of the IC design cycle and are handed over to IC foundries for IC fabrication. It was originally developed by Calma for its layout design system, "Graphic Design System" ("GDS") and "GDSII". Despite its limited set of features and low data density, it became the industry conventional stream format for transfer of IC layout data between design tools of different vendors, all of which operated with proprietary data formats. Initially, GDSII was designed as a stream format used to control integrated circuit photomask plotting. If your game is a single player one, you can easily store the Player reference when the Player spawns within the Spawn point and then use this reference when working with UI.GDS = Graphic Design System (see ) Remember, that in MP games there may be more players than one. When interacting with UI, the instructions require you to set which player you want the UI to show to etc.
