GDScpp is a C++ library that make GDS file manipulation easier.Even though GDScpp can be compiled as a stand-alone program, it is intended to be used as a library.

Version: 1.1

• Convert GDS data to ASCII.
• Easily create GDS files.
• Import GDS files.
• Extract the root GDS structures.
• Create a hierarchy diagram of all the GDS structure dependencies.
• Direct importing of GDS files with redundancy checking
• Create bounding box of all the GDS structures

The following packages is required to successfully compile and execute GDScpp.

apt install build-essencials cmake# for compilingapt install graphviz# for creating hierarchy diagram(dot file)

# Current directory: GDScpp rootmkdir build&&cd buildcmake ..make

A few examples are provided in theexamples folder to show some of GDScpp's functionality.

#include"gdsCpp.hpp"intmain(int argc,char *argv[]){  gdscpp fooGDS;  gdsSTR fooSTR;  fooSTR.name ="example";  std::vector<int> corX = {0,200,400};  std::vector<int> corY = {700,900,700};  fooSTR.PATH.push_back(drawPath(1,5, corX, corY));  corX = {200,200};  corY = {900,000};  fooSTR.PATH.push_back(drawPath(1,5, corX, corY));  corX = {0,150,150,250,250,150,150,400,400,0,0};  corY = {0,0,250,250,150,150,0,0,400,400,0};  fooSTR.BOUNDARY.push_back(drawBoundary(2, corX, corY));  fooGDS.setSTR(fooSTR);  fooGDS.write(fileName);return0;}

Translate GDS file directly to ASCII.

./gdscpp -i input.gdsor./gdscpp -i input.gds>> outfile.txt

Imports a GDS file into memory and exports a minimal GDS file out.

./gdscpp -rw input.gds -o output.gds

Calculates the root structures of the GDS file

./gdscpp -rs input.gds

generates a diagram of the hierarchical structure of the GDS file.

./gdscpp -r input.gds

• Create a map to easily find the structures
• Refactoring of GDScpp into a more standard library format
• Extract a desired GDS structure to a separate file

• Text and nodes are not fully supported.
• Box is currently not supported.

2020-06-11 Improved GDS read-in redundancy checking; AREF, BOX and TEXT is working; Bug fixes.2020-02-25 Updated Readme, added get_database_units_in_m function.
