</li>
These are the constraints which assign the I/O signals of the video module to the
appropriate pins of the FPGA on the XSA-3S1000 + XST-3.0 combination.
<p></p>
<li><strong><a name="item_video_2ebit"><em>video.bit</em></a></strong><br />
</li>
This is a compiled bitstream for the design that can be downloaded into the XSA-3S1000 + XST-3.0 combination.
<p></p>
<li><strong><a name="item_video_2d200_2eucf"><em>video-200.ucf</em></a></strong><br />
</li>
This is an alternate set of pin assignments to be used if the design is recompiled for
an XSA-200 + XST-3.0 combination.

<li><strong><a name="item_video_2enpl"><em>video.npl</em></a></strong><br />
</li>
Open this project file with WebPACK if you need to recompile the design.
<p></p>
<li><strong><a name="item_xsi2c_2eexe"><em>xsi2c.exe</em></a></strong><br />
</li>
This is a command-line program that allows you to initialize the control registers on the video decoder chip
through the parallel port of a PC.

<ul>
<li><strong><a name="item_step_1_3a">Step 1:</a></strong><br />
</li>
Set jumper J9 on the XSA-3S1000 Board to XS.
<p></p>
<li><strong><a name="item_step_2_3a">Step 2:</a></strong><br />
</li>
Download the default parallel port interface into the XSA-3S1000 (<em>\XSTOOLS\XSA\3S1000\dwnldpar.svf</em>)
if it is not already present.  (Running GXSTEST will do this automatically.)
<p></p>
<li><strong><a name="item_step_3_3a">Step 3:</a></strong><br />
</li>
Download the <em>video.bit</em> file to the XSA Board.
<p></p>
<li><strong><a name="item_step_4_3a">Step 4:</a></strong><br />
</li>
Connect a VGA monitor to the DB15 port (J3) of the XSA-3S1000 Board.
<p></p>
<li><strong><a name="item_step_5_3a">Step 5:</a></strong><br />
</li>
Connect a source of NTSC video to RCA jack AIP1A on the XST-3.0 Board.
<p></p>
<li><strong><a name="item_step_6_3a">Step 6:</a></strong><br />
</li>
Within a command window on the PC, type the command:
<pre>
  xsi2c -a B8 -scl_out_pin 2 -sda_out_pin 3 -scl_in_pin 15 -sda_in_pin 13 -w 3 6D</pre>
<p>This will enable the outputs of the TVP5150 video codec chip.</p>
<p></p>
<li><strong><a name="item_step_7_3a">Step 7:</a></strong><br />
</li>
Press the PB1 button on the XST-3.0 Board.  A frame of video from the video source will be
captured and displayed on the VGA monitor.
<p></p></ul>
