<H3>Summary:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
The <B>cif</B> command toggles between the view of the layout
|
||
|
|
as CIF (equivalently, GDS) layers, and the magic database
|
||
|
|
layers. The view of CIF/GDS layers is default, because the
|
||
|
|
representation of contacts is much clearer in the CIF/GDS
|
||
|
|
view. <P>
|
||
|
|
|
||
|
|
To view CIF/GDS layers in the 3D rendering window, it is
|
||
|
|
necessary to have rendering information in the technology
|
||
|
|
file for each CIF/GDS layer, presented in the <B>cifoutput</B>
|
||
|
|
section with the <B>render</B> keyword. This information
|
||
|
|
includes the style with which to render the layer, and
|
||
|
|
height and thickness information for each layer. Note that
|
||
|
|
this height and thickness is currently used only for rendering
|
||
|
|
purposes, and so values are effectively arbitrary. Height
|
||
|
|
and thickness values corresponding to the <B>magic</B>
|
||
|
|
database layers can be provided in the <B>extract</B> section
|
||
|
|
of the technology file, and is used for three-dimensional
|
||
|
|
geometry extraction as well as the 3D window viewing of the
|
||
|
|
<B>magic</B> database layers.

<H3>Implementation Notes:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
<B>cif</B> is implemented as a built-in <B>wind3d</B>
|
||
|
|
window command in <B>magic</B>. It can only be invoked from
|
||
|
|
a window created with the <B>specialopen wind3d</B> command,
|
||
|
|
or the <B>render</B> procedure. Note that the <B>wind3d</B>
|
||
|
|
window is only available when magic is compiled with the OpenGL
|
||
|
|
graphics option and invoked with <B>magic -d OGL</B>. <P>
|
||
|
|
|
||
|
|
Note that macros of the <B>wind3d</B> window are hard-coded,
|
||
|
|
and cannot be changed with the <B>macro</B>, <B>gmacro</B>, or
|
||
|
|
<B>imacro</B> commands. There is no "<TT>:</TT>" macro for
|
||
|
|
entering commands; to enter commands from the command-line,
|
||
|
|
use the <A HREF=../tk_path_name.html> <I>tk_path_name</I></A>
|
||
|
|
command. The default Tk path name of the <B>wind3d</B> window
|
||
|
|
is "<TT>.magic3d</TT>".
