OpenAccess is a community effort to provide interoperability, including unified data exchange among integrated circuit design tools through an open standard data API and reference database supporting that API for IC design. It is coordinated by the OpenAccess Coalition of semiconductor and EDA industry leaders, including Altera, AMD, Cadence, IBM, Hewlett-Packard LSI Logic, Renesas (formerly Mitsubishi, Hitachi and NEC), Freescale (formerly Motorola), NXP Semiconductors, ST Microelectronics, Sun Microsystems, Synopsys and Texas Instruments.
Client applications can access the OpenAccess database through APIs in multiple programming languages: C++, C#, Perl, Python, Ruby and Tcl.
