Austin, Texas--Feb. 23, 1998--Driven by demand for increasing library accuracy and consistency across deep-submicron design flows, the ASIC Council formally adopted an open library architecture enabling access to advanced ASIC libraries through an application programming interface (API) called OLA. Recognizing the need for greater flexibility to address modeling differences among silicon suppliers not afforded by current text formats, the Council's decision signals a shift to compiled libraries that can be accessed by multiple EDA tools. Other major benefits of this approach are increased designreuse permitted by portability of the underlying libraries, as well as higher levels of modeling abstraction essential in system-on-a-chip designs.
The selection was made on the basis of recommendations from a group of ASIC Council technical representatives following months of detailed analysis and in-house prototyping efforts using the latest silicon process technologies. After considering existing formats, the group elected to base OLA on the existing and proven Delay and Power Calculation Application Program Interface (DPC API), which is an eminent IEEE P1481 standards candidate through the successful joint efforts of SI2 and Open Verilog International.
The ASIC Council has elected to define the API to accommodate text formats by extending the Delay and Power Calculation Language and API so that it can represent functionality of the Advanced Library Format (ALF). Through the planned development of an ALF parser, libraries can be then be compiled by the existing commercially available DCL compiler. Thus any EDA vendor implementing OLA will have access to all compliant ASIC libraries. To assure preservation of existing investments, library formats such as Verilog, VHDL/Vital, SDF, and Synopsys's ".lib" will continue to be supported for EDAtools requiring access to timing and power data.
ASIC Council companies are expected to offer demonstration libraries with supporting EDA vendors at the Design Automation Conference this June with production versions available by year-end. The Council is encouraged by the early cooperation ofEDA vendors during the evaluation phase and the recent indications of public support from Ambit, Avanti, Cadence, Duet, Mentor Graphics, and Synopsys.
A Technical Advisory Board will be formed from among representatives of the ASIC Council and EDA vendors to guide the evolution of OLA beyond the initial version backed by the ASIC Council in coordination with the EDA Industry Council and Open Verilog International. The advisory board will be supported by SI2 as the contracted facilitator of both the ASIC and EDA Industry Councils.
