where <I>args</I> are any arguments to be passed to the <B>irsim</B>
|

program as they would from the command line. See the <B>irsim</B>

documentation for an explanation of its valid command-line

arguments.

<H3>Summary:</H3>
|
|
<BLOCKQUOTE>
|
|
The <B>irsim</B> command starts the <B>irsim</B> simulator. While
|
|
previous versions of magic did this by forking the <B>irsim</B>
|
|
process, Tcl-based <B>magic</B> can load the Tcl-based <B>irsim</B>
|
|
as a package directly into the interpreter. Commands for <B>irsim</B>
|
|
are added to the Tcl namespace and are available directly from the the
|
|
<B>magic</B> command line. <P>
|
|
|
|
As a Tcl script, the <B>irsim</B> command attempts to set up the
|
|
simulation arguments to ensure proper startup. It also checks for
|
|
a valid <TT>.sim</TT> file matching the layout, and generates one
|
|
if it does not already exist. <P>
|
|
|
|
A number of commands are available for viewing signal values directly
|
|
on the layout. For a complete description of these commands and
|
|
the Tcl-based <B>irsim</B> simulation environment, see the documentation
|
|
on <B>irsim</B>. <P>

<H3>Implementation Notes:</H3>
|
|
<BLOCKQUOTE>
|
|
<B>irsim</B> is implemented as a Tcl procedure that loads the Tcl-package
|
|
based version of <B>irsim</B>, then executes its startup procedure. The
|
|
<B>irsim</B> Tcl package itself is compiled and installed separately
|
|
from <B>magic</B>.
