A Cutting-Edge CAD Library for Layout Design

GDSTK: A Cutting-Edge CAD Library for Layout Design

In the ever-evolving landscape of design tools, the demand for efficient and robust CAD libraries remains paramount. Enter GDSTK (GDSII Tool Kit), a comprehensive C++ library and Python module specifically designed to simplify the creation and manipulation of GDSII and OASIS files. With a focus on complex layout design, GDSTK offers a wide range of features that cater to the needs of electronic chip design, planar lightwave circuit design, and mechanical engineering.

Embracing Complexity with Ease

One of the key features of GDSTK is its ability to perform Boolean operations on polygons, including AND, OR, NOT, and XOR operations. These operations are based on a powerful clipping algorithm that allows for precise manipulation and combination of complex shapes. The polygon offset feature further allows for inward and outward rescaling of polygons, enabling fine-tuning of layouts. Additionally, GDSTK provides efficient point-in-polygon solutions for large sets of arrays, ensuring optimal performance even with extensive designs.

Targeted Solutions for Specific Industries

GDSTK’s versatility makes it an ideal choice for various industries. In the field of electronic chip design, where precision and efficiency are paramount, GDSTK’s polygon operations and offset capabilities enable seamless integration of complex circuit layouts. Similarly, in planar lightwave circuit design, GDSTK offers the tools needed to create intricate waveguide structures with ease. And in the realm of mechanical engineering, GDSTK’s ability to manipulate polygons and perform Boolean operations opens up new possibilities for designing mechanical components and structures.

Unparalleled Performance and Efficiency

When compared to existing tools, GDSTK showcases superior performance and efficiency gains. A series of benchmarks comparing GDSTK to a well-known tool, Gdspy, reveals significant improvements in processing time across various functions. For instance, in analyzing 10,000 rectangles, GDSTK completes the task in just 4.87 milliseconds, compared to Gdspy’s 80.2 milliseconds, resulting in a 16.5x speed gain. Similar improvements are observed in other benchmark tests, solidifying GDSTK’s position as a cutting-edge solution for layout design.

Seamless Integration and Ease of Use

GDSTK offers an intuitive and user-friendly interface, making it accessible to both novice and experienced users. The Python module, which acts as a successor to Gdspy, can be installed easily via pip or Conda. It includes comprehensive documentation and utilizes popular Python libraries such as Numpy, making it highly versatile. Additionally, GDSTK provides cross-platform support, enabling users to work seamlessly across different operating systems.

Looking Towards the Future

GDSTK’s commitment to continuous improvement is evident in its active development community and support from the open-source community. Regular updates and new releases ensure that users have access to the latest advancements in layout design. Additionally, GDSTK encourages user feedback and incorporates it into future development plans, ensuring a user-centric approach and a focus on addressing real-world needs.

In conclusion, GDSTK revolutionizes the world of layout design, providing a comprehensive set of tools for complex CAD layouts. Its powerful features, superior performance, and seamless integration make it the go-to solution for electronic chip design, planar lightwave circuit design, and mechanical engineering. As GDSTK continues to evolve and innovate, it paves the way for a future where design tools are accessible, efficient, and empowering.
