Santa Clara, CA – Aug 9, 1999 - OEA International, Inc. announces the receipt of a contract from SEMATECH for the development of high accuracy design tools for deep submicron designs. The contract will significantly enhance OEA’s Chip Parasitic Extraction and Signal Integrity Verification (CPE&SIV) tools to help design VLSIs with geometries down to 130 nanometers. The OEA tools, along with tools from other EDA vendors, will be compatible with Chip Hierarchical Design System (CHDS technical data) tool standard being promoted by SEMATECH and its member companies. OEA is the key contributor in providing high accuracy parasitic extraction for timing calculation and power distribution network analysis tools.

As indicated in the National Technology Roadmap for Semiconductors, feature size will continue to scale down and chip sizes will continue to grow. As this trend continues, interconnect has become the major factor in determining timing and performance in VLSI circuits. It has become necessary to model critical interconnect more accurately in order to meet the needs of timing and signal integrity. OEA, working with SEMATECH, will be meeting these needs by enhancing five major products, NET-AN a 3-D Critical Net Parasitic Extractor; P-GRID, a 3-D Power Distribution Network Analyzer; P-PLAN and RING Designer for Power Distribution Network Floorplanning and Design Rule Analysis; and TECH-AN, an IC Process Statistical Analyzer. OEA will also use its expertise to study the effects of on-chip inductance and advise SEMATECH member companies on the need for inductance extraction in VLSI design.

High Accuracy Net Parasitic Extraction
NET-AN is a three-dimensional IC field simulator for extracting accurate RCL SPICE parasitics of selected critical nets on an IC. NET-AN graphically extracts, builds a 3-D model, and simulates a net, tree, or critical path allowing the user or the system to automatically assign nodes. SEMATECH driven enhancements will include adding multi-net capability, Application Program Interface (API) to formula-based full chip extraction tools, integration into the SEMATECH CHDStd design database, and further speed and advanced technology enhancements.

IC Process Statistical Analysis Tool
OEA will develop a new innovative product, TECH-AN, which statistically analyzes manufacturing process variations and determines probabilistic variations in electrical RC parasitics. The data can then be used with floorplanners, routers and other extraction tools for performance driven design.

Power Distribution Network Analysis and Floorplanning
P-GRID is used for post-layout analysis of the power or ground interconnect networks on an IC for IR (Voltage) drop and electromigration violations. P-GRID extracts, builds a 3-D model, and simulates power distribution networks reporting excessive drops in supply voltage or excessively high current density levels that will lead to early chip failure. One of the most important steps in designing a large VLSI is setting up proper design rules for power and ground interconnect. For optimizing the geometric configuration of power and ground rings, internal power rails, and ring voltage source pad locations, OEA has developed P-PLAN. Common problems of ground bounce and simultaneous switching noise on I/O rings are avoided by proper analysis with a new OEA tool called RING Designer. Enhancements to P-GRID, P-PLAN, and RING Designer will include interfacing to the SEMATECH CHDStd design database, speed improvement and further technology enhancements.

With these SEMATECH driven enhancements to OEA products, SEMATECH Member Companies will be reaping the benefits of early access to the latest OEA product releases to enhance there competitive edge in design capability.
