EDWin XP 3-Dimensional
EDWin XP has been packed with the most
exciting and comprehensive step towards the design of electronic circuit with
the concept of three-dimension (3D). Designed electronic circuits (PCB) are
usually housed inside cabinets or any intricate structures where spacing between
different boards placed has to be dealt with prudently. Working in 3D
environment facilitates optical design check. It provides an in-depth analysis
of the board density and a realistic view of a designed PCB.
The concept of 3D has been incorporated into Layout Editor and Library Editor.
Layout Editor consists of 3D Board Viewer and 3D Trace Viewer. Library Editor
allows editing and creating of 3D library packages and cabinets. Tools have been
provided to assist the user view the board and package from various directions
and from different angles.
Let us have a look at how 3D has been implemented in Layout & Library
In Layout Editor 3D Board Viewer can be
invoked from menu Tools ->3D Board Viewer.
3D Board Viewer gives a real life view of the designed board in various
perspectives and directions. It gives idea on how the components are
located, whether there is risk of friction between components due to
their height and shape, the side on which components are placed, etc.
This helps to take any design changes if required.
3D Trace Viewer
In Layout Editor 3D Trace Viewer can be
invoked from menu Tools ->3D Trace Viewer.
3D Trace viewer helps to visualize all the physical connections on
board. Traces, vias, buried vias, and copper pour elements can be easily
visualized. It helps to examine in detail the path taken by traces of
each net .It makes the traces present in internal layers (A to Z)
visible as shown.
in Library Editor
In Library Editor, 3D have been bundled
with Package Creation. Also a new concept of Board Cabinet has been
Editor :- In Package Editor,
apart from 3D View Control dialog, a number of function and
option tools has been provided to assist the user in editing and
orientating the package. A package created in the usual (2D)
manner can be converted into 3D using these tools. One can enter
the 3D mode from the menu Edit/ 3D Viewer. Package Viewer helps
to view the package in 3D. To begin with, when you open Package
Editor in 3D Edit mode, you see a small rectangular box with a
round pad on it. This is the same default pad, which appears
when a new package is opened in Package Editor. In other words,
whatever is present on the workspace in normal Package Editor
gets depicted in 3D mode.
Board Cabinet Editor
spacing and positions of boards in cabinets or any intricate
mechanical structure may be adjusted using Board Cabinet
Editor present in Library Editor.
