[ Longest-Path Routing ]

• Obstacle-Aware Longest-Path Routing with MILP Solvers

[ The PPPP Program ]

• PPPP is used for partitioning parameterized orthogonal polygons into parameterized rectangles. With this program, it is possible to build rectangular corner stitching data structure for parameterized VLSI layouts.

[ OwlVision GDSII Viewer ]

• The aim of this project is to develop a GDSII viewer by using Java programming language. Efforts will be made especially on ease-of-use, efficiency, and capacity.

[ Layout Generator ]

• The program can randomly generate a flattened VLSI layout in ASCII file. We can then translate the ASCII file into GDSII Stream Format.
• The generated layout can be used for testing layout tools.

[ Generate Space Tiles for Corner Stitching ]

• Partition the space bounding box, a rectangle that covers many polygons, into rectangular strips
• This is the basis for constructing Corner Stitching data structure

[ Orthogonal Polygon --> Rectangles ]

• Partition an orthogonal polygon into rectangular strips
• Use plane sweep techniques
• This is the basis for constructing Corner Stitching data structure

[ GDSII Viewer ]

• UQ GDSII Viewer
• Free GDSII Viewer

[ GDSII --> ASCII ]

• Translate GDSII Stream Format (binary) to a text file (ASCII)
• Java version

[ GDSII --> ASCII ]

• Translate GDSII Stream Format (binary) to a text file (ASCII)
• C version

[ ASCII --> GDSII ]

• Translate a text file to a GDSII file
• GDSII generator

[ GDSII Hex Dump ]

• Dump the hexadecimal code from GDSII Stream Format
• C version

[ GDSII Layout Files ]

• VLSI layout examples (in GDSII Stream Format)
• Inverter, NAND, XOR gates are included
