GOLFA Versatile Layout Platform

Brochure

OVERVIEW

GOLF is a production-proven OpenAccess-based layout platform adopted by world-class companies of fabless design, layout and design service, semiconductor foundriesand flat panel display manufacturers.GOLF features powerful layout viewing and editing functions, intuitive GUI, flexible customization and more extension, with both simplicity in GUI and flexibility in design flows. Its API with C++/TCL/PERL/PYTHON interface (and more on demand) helps users developing a variety of applications. GOLF capabilities facilitate great customization for different applications, such as custom layout functions, analog layout automation (schematic or constraint-driven layout, etc), testchip structure layout automation (from PCell designer to IP block/component and to chip-level layout) or panel-level layout integration and automation.

PCELL DESIGNER

Evolved with the experiences and feedbacks of PCell programmers and layout engineers, GOLF provides a visualized integrated development environment (IDE) for parameterized layout design, preview, testing, debug, and documentation on layout directly. It is based on AnaGlobe’s patented highly flexible and reusable hierarchical parameterized layout generator. The OpenAccess (OA) objects of the existing layout can be parameterized directly. More complicated objects such as polygon text, fingers, spiral, and runway are provided. Layout can be composed by geometric operations with object lifetime control. User-defined code (in C++/TCL/PERL/PYTHON) can still be integrated as well.

 

TEST STRUCTURE LAYOUT AUTOMATION

  • Interactive test modules generation
  • Friendly straight-forward flow
  • User-configured probe-lines (pad, slots, label and routing)
  • Excel split table driven auto layout
  • Test modules generation

 

 

 

SCHEMATIC-DRIVEN LAYOUT (SDL)

GOLF SDL operation honors a hierarchical connectivity model working simultaneously at all levels of hierarchy. This facilitates designers aware of the complexity of interactions through full design hierarchy, and supports one-to-many mapping across multiple hierarchy levels. For example, GOLF will alarm connectivity errors if a net is short or open; layout designers to view different layout hierarchies at the same time for efficient ne
t tracing or debugging. Such cross-probing of hierarchical net-tracer and Short-indicator can easily highlight the problematic nets, significantly reduce efforts and speed up the debugging efforts.

  • Layout realization from schematic using PCell devices
  • Transistor/Resistor/Capacitor/Inductor PCell mapping
  • Mapping from predefined sub-circuit layout
  • Analog placer with multiple constraints: Symmetry, Proximity, Preplaced, Fixed-Boundary-Block, Boundary, Minimum Separation
  • Analog router with multiple constraints: Symmetry, Topology-Matching, Length-Matching, Length-Ratio-Matching, Bounding
  • Supports PCell transistors merge/split/stretch/folding functions
  • Cross-probing between schematic/layout and netlist browser
  • Connectivity driven editing: net propagation when creating wire, net flylines,real-time short and open detection
  • Schematic comparison in ECO flow
