Generic GDS UTILITY

• The utility is developed by Albert Li since 1996.

Purpose:

The main purpose of this Generic GDS utility is to convert binary GDS-II file to a readable text format (GDT), so user can validate the design content, modify or manipulate the content using simple script languate such as tcl or perl without decoding the GDS-II binary format.

How to build the executable

1. Compile Utility Library

• libutil - general utility routine, such hash, list, link ....

• libgds - GDS-II reader/writter

  Example:

  % cd libsrc/
  % make clean
  % make update

2. Build Main Program

• gds2gdt - convert GDS (binary format) to GDT (text format)

• gdt2gdx - convert GDT (text format) to GDX (binary format)

• gds2gdx - convert GDS (binary format) to GDX (binary format)

  Example:

  % cd main/	
  % make clean
  % make publish

3. Run Test Prgoram

• TEST1 - check GDS2GDT+GDT2GDX (muxdelay.gds <=> muxdelay.gdx)

• TEST2 - check GDS2GDT (muxdelay.gdt <=> output.gdt)

• TEST3 - check GDS2GDX (muxdelay.gds <=> output.gdx)

  Example:

  % cd run/	
  % make TEST1
