www.easic.com

The eASICore has been successfully proven in silicon on UMC's 0.18-µm, six-metal-layer process. According to the company, this configurable core delivers high performance and high density. The eASICore is now characterized at the silver level (hardware available, silicon available). It will be represented in UMC's Gold IP catalog. The fabrication is done in a conventional semiconductor process. Due to its proprietary technology, eASICore significantly reduces the number of mask sets used for programming. The company says this configuration leads to time and cost savings. This technology combines an SRAM lookup-table cell with metal mask programmable interconnection. This configuration delivers close to a standard cell's performance and density as well as an FPGA's ease-of-design.

The eASICore and supporting EDA tools are now available for implementation in silicon by chip developers using UMC's 0.18-µm process technology.

(408) 565-0111; www.intime-online.com

DesignArena is a pre-Register Transfer Level (RTL) design-prediction environment for ASIC and SoC designs. According to the company, this tool offers designers a high-level, pre-RTL look at their designs. Predictive views of the design include size, power, and performance estimates based on user-provided design data.

Users select the technology library. Users also provide the estimated gate count and the number and size of memories, intellectual-property building blocks, and user-defined blocks. Clock information and voltage domains must also be defined. The user supplies the number and type of signal pins employed in the design. Once the user places the memory and intellectual-property blocks, the power buses are automatically routed. Based upon the design criteria, DesignArena calculates the number of power and ground pad cells required.

Automatically placing these power and ground pad cells where required, DesignArena offers a complete pre-RTL view of the design. Performance feedback provides guidelines for logic in individual clock domains that can be tracked by other tools for conformance during RTL design. According to the company, DesignArena can be used as the starting point for its DesignWarrior integrated RTL development environment. Available now, DesignArena runs on Sun workstations. Pricing begins at $37,500.

(610) 644-1300; fax (610) 296-0657; www.vishay.com

The Si9912 and Si9913 single-input dual MOSFETs offer an extended input-voltage range of 4.5 to 30 V. The supply voltage ranges from 4.5 to 5.5 V. The devices are packaged in an 8-pin SOIC. They integrate drivers capable of switching a 3000-pF load with a 60-ns propagation delay. A transition time of 25 ns is featured. This fast switching speed minimizes switching losses and increases power efficiency.

The devices are outfitted with an integrated bootstrap diode on the high-side driver. They are capable of handling the high-voltage slews associated with "floating" high-side gate drivers. The MOSFETs offer a 1-A drive current that supports switching frequencies up to 1 MHz. According to the company, the Si9912 and Si9913 are an optimal choice for high-frequency, high-current converters. Integrated protection features include an undervoltage lockout and an automatic break-before-make circuit that prevent shoot-through current in the external MOSFETs. This ensures that the high-side and low-side MOSFETs do not operate at the same time. The Si9913 features a synchronous enable pin used to enable the low-side driver. The Si9912 provides a shutdown pin that enables the driver, with a power-efficient quiescent current of less than 5 µA when the driver is disabled.

While samples of the Si9912 and Si9913 are now available, production quantities will be available next March. For 25,000-unit quantities, the devices cost $1.17.
