go-gds

go-gds allows for encoding/decoding of Calma GDSII binary files.

Features

• Decoding binary files to go types
• Encoding go types to binary
• High-level api functions to extract geometries, labels and paths, separated into cells and layers

Missing

• Functionality to manipulate geometries, paths, labels, cells and layers
• Entire path starting from geometries to binary

Example

fh, err := os.Open("mygds.gds")
if err != nil {
    log.Printf("could not open test gds file: %v", err)
}
defer fh.Close()

library, err := ReadGDS(fh)
if err != nil {
    log.Printf("could not parse gds file: %v", err)
}
// Prints basic library information, cells and contained elements
fmt.Print(library)


// Returns map of layer/datatype -> polygons for specified cell
layermap, err := library.GetLayermapPolygons("mycell")
if err != nil {
    log.Printf("could not extract layermap polygons: %v", %v)
}

// Show layers and polygons
fmt.Print(layermap)
