San Jose--August 17, 1998--The Virtual Socket Interface Alliance (San Jose) announced that it has released its on-chip bus specification for the design, integration, and testing of multiple functional blocks on a single piece of silicon. Developed by VSIA's On-Chip Bus (OCB) Development Working Group and entitled "On-Chip Bus Attributes, Version 1.0," the specification provides a description of the requirements for on-chip bus documentation, physical deliverables, and technical bus attributes. The document can be accessed and downloaded from the VSI Alliance Web site.
The OCB Attributes specification also defines a minimum set of attributes for system integrators, virtual component developers, and bus developers to choose from while using or developing system or peripheral on-chip buses. A set of on-chip bus design guidelines and a glossary of common bus terminology are provided as well.
The OCB data deliverables include several open standard formats such as Verilog (IEEE 1364-1995) and VHDL (IEEE 1076-1987). The document includes a user guide that contains a detailed list of categorized deliverables such as signal definitions, bus operation, configuration space, core isolation, and implementation specifications. The user guide also provides information to support the user and provider of VCs: bus development tools, physical attributes, timing analysis, simulation models, bus implementation tools and a glossary of terms.
