EDWin - Electronic Design for Windows is one
of our first, and the best (we like to think), system, running completely under
Windows 3.1, or higher (no problems noted under Windows95 or Windows NT)
It,like the EE Designer III/The Professional (running under MS-DOS), features
almost everything you´ll ever need to get your design jobs done in the most
EDWin is a CAD/CAE software package
providing an electronic engineer with computerized tools to capture an
electronic circuit in the form of schematic diagram and/or PCB layout. The final
result of work with EDWin is documentation for manufacturing of printed circuit
boards. EDWin features seamless integration between all its modules namely Schematic Capture, Layout Design, Postprocessing and Simulation, which is possible, thanks to
a totally integrated design database structure facilitating automatic front and back annotation.
EDWin can be visualized as a package comprising of mainly 5 task-oriented modules
namely Schematic Capture, Layout Design, Postprocessing,
and Library Editor.The user may start creating the integrated
design database either by capturing the circuit in the form of schematic diagram
or by designing its PCB layout. It will be front annotated to Layout Design in
case of the former and back annotated to Schematic in case of the latter. This
concept allows building both parts of the circuit design simultaneously.
With version 1.5X a new copper pour is included. There are new search engines and list
programs for the libraries. A new Auto-Help will assist you to cut down the learning
curve. Arizona router now includes Fan-Out and a possibility to define your own
strategies. All the modules contain not only the basic tools needed, but also work-easing
extras, like the Schematic Capture's autoplacer, and also the possibility to customize
your own toolboxes to make your work even smoother and more efficient.
Thanks to the Open Database concept implemented in EDWin, you also have the extra
option of being able to "plug in" and interface with your favourite 3rd party
applications or begin your work at any given point - schematics or layout, it doesn't
matter as netlists and device descriptions are shared between the system's modules.
Schematic Capture provides editing
tools to create a schematic representation of the circuit. The Capture process
starts with the placement of schematic components for which outline, gating and
pinout data may either be created new or fetched from Part Libraries.
Interactive routing of wires (electrical connections) creates connectivity
between the components of the circuit (netlist).
Layout Design module provides tools for creation of
layout components (silk-screens and footprints), netlist and routing of traces. Normally,
all necessary components and netlist information is automatically transferred from
schematic diagram to the layout (front annotation). Other features included are automatic
placing of components, automatic clearance and connectivity checking and autorouting of
traces. All changes concerning netlist and circuit components, introduced during PCB
layout design process, are automatically updated in the Schematic Diagram (back
Postprocessing involves converting the design data
(layout) into manufacturing and validation outputs. Postprocessing module includes
features for generation of PCB manufacturing documentation like artwork and documentation
printouts, outputs for photoplotting and Numerically Controlled (NC) drilling.
Simulation module allows validating the circuit
behavior during the process of Schematic Capture and/or Layout design i.e. before actually
manufacturing the PCB. This module includes a Diagram Generator
for graphical presentation of the simulated results, Mixed Mode
Simulator for combined AC and DC analysis, EDSpice Simulator
for SPICE simulation and a Thermal Analyzer for analyzing the
effect of temperature parameters on the working of the circuit.
Library Editor module allows to create new elements
as well as edit elements already existing in Part Libraries - comprising of Device
description, Schematic symbols, Layout symbols and Padstacks. A Library Viewer is also
included which allows visualizing the contents of the Part Libraries as well as
cross-references between Device descriptions, Schematic Symbols and Layout Symbols.
Auto Help feature provided in the options menu item of
EDWin Main Menu allows to toggle on/off the automatic help topic
display facility. Auto Help feature helps the user to navigate through the System with
automatic help popping up whenever the user does an event in the system.
Ctrl + F1 invokes Context Sensitive help for the currently active topic.
