Group Long Description:

OpenAccess Gear (OAGear)

February 17, 2010: OAGear was an academic community project on the Si2 site from 2005 through 2009. The site has been discontinued. The OAGear project is currently suspended and unsupported - however the latest release and the forum discussions may be of educational use to many. Si2 has decided to offer OAGear here as an unsupported project.

OpenAccess Gear (OA Gear) is a toolkit for extending the utility of OpenAccess, a powerful database for EDA tools.

OA Gear is targeted towards academic researchers who wish to use OpenAccess and are looking for software components to integrate into their own research. However, industry professionals are also welcome to use OA Gear. To this end, OA Gear is released under an open source license. The file COPYING is packaged in release downloads and contains the open source license.


OA Gear currently consists of the following tools:

  • Static timing engine (OA Gear Timer)
  • Extensible graphic user interface (OA Gear Bazaar)
  • Placement interface (OA Gear CapoWrapper)
  • Functional/logical representation package (OA Gear Func)
  • And-inverter graph package (OA Gear Ai)
  • Benchmarks
