<H3>Summary:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
The <B>wire</B> command allows quick generation of wires on the
|
||
|
|
layout. Some of these commands are bound to mouse button events
|
||
|
|
in the wire tool, making a convenient interface for fast wiring
|
||
|
|
where full netlist routing is not required. Due to the presence
|
||
|
|
of the wire tool, most of these commands are not typically called
|
||
|
|
from the command line. <P>
|
||
|
|
|
||
|
|
The <B>wire segment</B> command can generate non-Manhattan segments.
|
||
|
|
All other wiring commands generate only Manhattan routes. This
|
||
|
|
command places wire segments in relation to the <I>centerline</I>
|
||
|
|
coordinates specified by <I>x1 y1</I>, <I>x2 y2</I>, and so forth.
|
||
|
|
By default, wires are drawn with an endcap extension of one-half
|
||
|
|
the wire width. The <B>-noendcap</B> option causes the wire to
|
||
|
|
end at the coordinate, with no extension. The <B>wire segment</B>
|
||
|
|
command is intended to be used from Tcl scripts for automatic
|
||
|
|
layout generation.
