=== Overview ================================================================= The GDSII Ruby Library provides an easy-to-use interface using Ruby to reading and writing GDSII files. Details may be found in the "doc" directory or by running "rdoc" on the "lib" directory. Contributors: - Jim Freeze - Ben Hoefer - James Masters - Matt Welland - Dan White Project webspace: http://rubyforge.org/projects/gdsii/ This library is released under the MIT License (see LICENSE.txt) === Installation ============================================================= The "installation" is easy - simply add the contents in the "lib" directory in this package to a directory where Ruby is installed or set the $RUBYLIB environment variable to include the "lib" directory. === Testing ================================================================== The GDSII library has been tested on Windows XP, SuSE Linux, SunOS, and HP-UX. To test the library on your own platform and configuration, a number of test suites are located in the "test" directory of this installation package: * test_gds_group.rb A unit test of the high-level GDSII methods. * test_gds_record.rb A unit test of the low-level GDSII methods. * h_pthru.rb Uses the GDSII high-level methods to read in a GDSII file and then write out the same GDSII file. The file should be identical - or at least just have just EOF null-padding differences. * l_pthru.rb Uses the GDSII low-level methods to read in a GDSII file and then write out the same GDSII file. The file should be identical - or at least just have just EOF null-padding differences. * h_write.rb Uses high-level GDSII methods to write out a number of GDSII records using many of the available method calls. This can be useful to verify that the GDSII library is working and the output file can be compared against the file found in ./test/baseline/h_write.gds to ensure that the platform is reading and writing GDSII properly. === Utility Scripts ========================================================== A few utility scripts have been included in the "bin" directory for general purpose use and/or for reference in using the Ruby GDSII library: * gds2rb Translates a GDSII file into a Ruby script containing commands to recreate the GDSII file. This might make custom edits to a GDSII file easy by post- processing the script through automation or by hand before running the script to produce an output GDSII file. * gdsdebug A detailed GDSII "dump" program that can be used to debug issues with a GDSII file that may be somehow corrupt or may be causing the GDSII Ruby file read methods to fail. * gdsdump A conversion of GDSII data to the "L" file format (ASCII). This can make quickly reviewing GDSII file contents through text very easy. * gdslayers Lists all layer and data types in the GDSII file. * gdssremove Removes the specified structure(s) from the GDSII file. * gdsssplit Extracts the specified structure(s) from the GDSII file and creates separate files for each of the extracted structures. * gdsstats Reads a GDSII file and produces a statistical summary of the contents of each structure in the file. * gdsstructs Lists all structure names found in the GDSII file. * gdstree Prints a hierarchical tree of structures in a GDSII file.
