Viewlogic Bridges Electronic and Electro-Mechanical Design
Marlboro, MA--May 27, 1997--Viewlogic Systems Inc. (Marlboro, MA) announced the company's entry into the Electro-Mechanical/Electronic Design Automation (EM/EDA) market. ViewCable, an environment for EM/EDA design capture and integration of best-in-class EDA tools, is the first of a series of products fromViewlogic's Advanced Development Group for electronic design and verification of electro-mechanical systems interconnected through cables and wire harnesses. ViewCable supports the full range of EM physical attributes for component packages and cabling.
In effect, ViewCable is a bridge between 2- and 3-D physical design, and the effects of interconnection physical attributes on the electronic performance of the combined system. ViewCable supports a full suite of EDA tools, including Analogy's Saber and generic Spice simulators. It supports suchViewlogic tools as the ViewSim gate-level simulator, SpeedWave VHDL simulator, and Chronologic VCS Verilog simulator. Mixed-signal simulation is available through theViewlogic Fusion interface.Viewlogic's Quad XTK product is supported for signal-integrity analysis along withViewlogic's QUIET for EMI/EMC analysis.
ViewCable brings two new features to EM/EDA design: a single, integrated design environment for EM/EDA design entry, simulation, and verification; and a common design database for component and cable/wire harness electrical and physical attributes. This common database gives electrical and mechanical design teams equal access to system attribute data for the first time.
The single, integrated design environment was created through development of new technologies that incorporate the physical design aspects needed for defining physical wires, cables, bundles, harnesses, and equipment. The new technologies also allow ViewCable to drive physical design for manufacture and provide a framework for analysis and simulation, while maintaining the familiar look of the electronic/electrical system and electro-mechanical components for documentation purposes. Electro-mechanical designers are given access to the full suite ofViewlogic best-in-class design tools, including analog, digital, mixed-signal simulation, signal integrity, and EMI/EMC analysis tools.
Significant features of ViewCable for design capture are a series of commands that enable engineers to define cabling and wire harness constructs from a logical design starting point; a wire databook to make generic wires into specific physical wires with the appropriate attributes for manufacture; and a user-extendible design rule checker, used to validate the design. Other features help automate the process of component placement and definition, which is especially important in the insertion of fuses and splices.
Equally important, the common design database for electrical and physical attributes allows the mechanical and CAD/CAE design teams to share data electronically, without the need to manually re-enter data in one design domain when changes are made in the other. This allows the results of electrical design to be immediately useful to both design teams in order to find and fix electro-mechanical design problems much earlier in the system design flow. The benefits are faster system development, reduction of cross-domain design errors, and improvement in the quality of system electrical characteristics.
Realistic application of customer designed cable/wire harness assemblies is achieved through bi-directional interfaces to popular mechanical design software products, including CATIA from Dassault Systemes and Harness Designer from Structural Dynamics Research Corp. Libraries of cable/wire harness components are also available and give the EM/EDA designer access to cable/wire harness components that include the physical characteristics of wires, connectors, and packages. These libraries support EM/EDA design verification at the subsystem level instead of at the individual component level.
ViewCable is scheduled to ship on popular Unix platforms in June, with the Windows-NT release scheduled for the fourth quarter of 1997. Pricing for the product series begins at $14,700 (network license).
