In 2012, Cadence Design Systems contributed a specification describing the extension of OpenAccess to represent multi-pattern technology, aka coloring. That specification has been a guide for developing the newest version of oaxColor extension, Release 1.1.
Developed by the OpenAccess Coalition Coloring Work Group, Release 1.1 extends the OpenAccess API, allowing users to implement their own (usually proprietary) process for multi-pattern technology. The work group has implemented everything described in the initial document, so the extension is effectively completed in this latest release. The work group is alert for possible bugs and enhancements, but the path to implementation should be uninterrupted by changes to the extension moving forward.
In addition to C++ for use with the OpenAccess Reference Implementation, Python and Ruby are supported companions to the oaScript API.
Congratulations to the Coloring Work Group, led by Ben Hoefer and Rajiv Subramanian of Intel, for their contributions to the OpenAccess Coalition. Release 1.1 is available to Si2 members here.
