Tool set hones pc-board automated-assembly processes.
Sequence Editor, a tool for evaluating, optimizing, and generating pc-board and MCM automated-assembly programs, helps reduce manufacturing costs and maximize yields. By plugging seamlessly into the Visula PCB/MCM Layout Editor environment, Se-quence Editor has direct access to the Visula CAD database, which provides the added benefit of eliminating errors that often occur when translating data into other CAM formats. The software analyzes insertion sequence, evaluates the number of head and bank changes, and calculates the magazine changes for a range of assembly equipment. From $18,000. Zuken-Redac, Santa Clara, CA. (408) 562-0177.
VHDL and analog simulators run under Windows NT.
VeriBest Release 14.5 brings two new simulators, VeriBest VHDL and VeriBest Analog, and a signal-integrity-analysis tool for high-speed pc-board design to the Windows NT environment. VeriBest VHDL uses an intermediate format with the language analyzer, which ex-tends its capabilities to include a Verilog analyzer, as well as the proposed analog HDL (Verilog-A and VHDL-A) for mixed-language simulation within a single simulator. The VeriBest Analog simulator ports the Apex analog simulator and Intergraph's VLABPlus user interface to Windows NT. VeriBest VHDL, VeriBest Analog, and VeriBest PCB Signal Analyzer cost $10,000 each. VeriBest Inc, Boulder, CO. (303) 581-2300.
Verification environment enhances debugging and analysis.
Quest II verification software for complex ICs cuts emulation, debugging, and analysis time. The Quest II suite comprises a unified database, a faster compiler, an improved de-bugger, and a range of design-analysis tools. The device also features tighter integration with the HDL-ICE 2.0 bilingual RTL ICE. A fast waveform viewer quickly manipulates trace data acquired during emulation, and a drag-and-drop browser lets you view designs at any level of the hierarchy. Quest II costs $125,000. The HDL-ICE 2.0 software costs $45,000 for Verilog or VHDL versions. Quickturn Design Systems Inc, Mountain View, CA. (415) 967-3300.
Web service accesses component databases.
AspectOnline is a Web-based subscription service that gives you desktop access to the vendor's VIP family of component databases. As-pectOnline provides powerful search and retrieval capabilities based on attributes of 1 million components from >600 suppliers. In addition to attributes, you can conduct searches based on vendor cross references, comparisons, part numbers and descriptions, and relationships. The cost of the service starts at approximately $1000/user/year, depending on the number of databases accessed. Aspect Development Inc, Mountain View, CA. (415) 428-2700.
Synthesizable cores al-low upgrade to 64-bit PCI-bus implementation.
These 32- and 64-bit PCI 2.1 synthesizable cores provide 32 possible configurations and let you upgrade from a 32- to a 64-bit implementation without changing the application portion of the design. The cores contain a set of synthesizable building blocks and are quickly configured to specific requirements without source-code modification. Cores include a flexible FIFO implementation and hooks to support multiple functions from a single PCI-bus interface. Prices for core licenses start at $50,000 in Verilog or VHDL. Sand Microelectronics Inc, Santa Clara, CA. (408) 235-8600.
Training package in-cludes PC-based VHDL simulator.
A
special edition of the PeakVHDL simulator comes with a demonstration CD-ROM and
a 450-pg textbook, VHDL Made Easy. The training-edition software differs
from the $1300 PeakVHDL professional version in that is does not include
source-level debugging, accelerated libraries, or support for VHDL's
configuration features. Even so, you can use the training edition for practical
design projects because there is no design-size limitation. The bundle costs
$499. Accolade De-sign Automation Inc, Duvall, WA. (206) 788-3768.
Integrated tools speed RFIC design.
The RFIC Simulation Suite combines a broad range of high-frequency simulation technologies with accurate models in a dedicated package tailored for RFIC design. Offered for both the Series IV and Microwave Design System software environments under Unix, as well as the PC platform in Series IV, the basic suite consists of a linear simulator, nonlinear simulator, statistical design package, custom model-development kit, and Spice netlist translator. Prices start at $46,000. Hewlett Packard, Santa Clara, CA. (800) 452-4844.
Design tool generates pc-board rules.
A rules engine converts, edits, and generates electrical and physical rules for efficient pc-board design. Designated UniRule, the stand-alone tool permits critical analysis of physical effects and what-if optimizations early in the design process. Once the rules engine collects rule attributes, UniRule guides you through the basic menu structure for setting rules in electrical terms. Another menu guides the calculation of constraints for physical design, letting you add emissions and signal-integrity limits, as well as timing constraints. A single node-locked Unix or Windows NT copy costs $10,000. UniCAD, Westford, MA. (508) 692-8446.
Schematic-capture package eases pc-board de-sign.
The System Designer schematic-capture program runs on Unix workstations, as well as PCs under Windows NT or Windows 95. The software provides on-line documentation and accepts both parts-based and generic design methodologies. You can add generic symbols and give them specific part properties later in the design cycle, allowing a "what-if" analysis before the component is added to the corporate parts library. Circuit data is exchanged with other schematic editors using EDIF 200 schematic view. System Designer, which includes a component browser and net browser, works with all of the vendor's layout products. Prices start at $5000. Zuken-Redac, Santa Clara, CA. (408) 562-0177.
Kit supplies silicon prototype of synthesizable µP.
A silicon evaluation module of the VZ80 synthesizable HDL 8-bit µP core lets you verify software in real time using actual silicon without the expense of an ASIC's NRE charge. The core has been synthesized into 0.8-µm CMOS and optimized for an area requiring only 6600 gates or a die size of 8 mm2. It achieves a clocking rate of as high as 18 MHz. The VZ80-ES1 evaluation kit, which includes a VZ80 84-pin PLCC prototype and complete documentation, costs $1000. VAutomation Inc, Nashua, NH. (603) 882-2282.
Cycle-based simulator runs under PC operating systems.
SpeedSim/3, a cycle-based, digital-logic simulator that operates on all major Unix platforms, comes in versions for Windows NT and Linux. With V2.4, you can augment the Unix and RISC workstations in your development environment with high-powered, lower priced PCs. SpeedSim/3 V2.4 costs $35,000. SpeedSim Inc, Westford, MA. (508) 251-3377.
PLD-design software gains timing-model generators.
Release 3.5 of PLDesigner-XL generates timing models for use in timing simulations on PLDs before moving the design to actual hardware. The standard timing-model generator models the device architecture, as well as propagation, input-to-output, setup, and clock-to-output delays in VHDL or Verilog. For high-speed designs, the advanced generator models as many as 50 values in Verilog, VHDL, or VITAL-95 VHDL. Prices start at $995 for the standard timing-model option and $1995 for the advanced option. Minc Inc, Colorado Springs, CO. (719) 590-1155.
Software builds memory models for Verilog/VHDL simulation.
Memory Modeler lets you create models for memory components and immediately use them in your designs. Encompassing an interactive debugger and testbench support built around client-server technology, Memory Modeler accelerates debugging and regression testing. You can use the software with Cadence Verilog-XL, Chronologic VCS, Frontline PureSpeed, and Model Technology V-System/Plus Verilog simulators, as well as Cadence Leapfrog, Model Technology V-System, Synopsys VSS, Vantage Optium, and Viewlogic Fusion VHDL simulators. Memory Modeler runs under SunOS 4.1X, Solaris 2.5, and HP-UX. Single-node prices start at $3500. DenaliD Software Inc, Palo Alto, CA. (415) 325-7241.
