R1 is unpopulated on the XC2C64A development board

</p><p>This designs adds a second LED and connects it to the push button through an inverter.
</p>
<ul><li>Input from BUTTON enters the CPLD through an input buffer (IBUF)
</li><li>The BUTTON signal connects to LED (D1) through an output buffer (OBUF) as before
</li><li>INV is a new schematic element that inverts the BUTTON signal before it connects to a second output buffer (OBUF) and LED_INV (D2)

NET &quot;LED_INV&quot; LOC = &quot;P38&quot;;</pre>
<p>Input and output markers in the schematic are mapped to actual CPLD pin numbers in the UCF file. This is an example UCF file that defines the three IO connections on the development boards.
</p>
<ul><li>The Pxx numbers are the actual pin number on the CPLD. Easy.
</li><li>ISE has a GUI utility to assign pin numbers, but it doesn't work with CoolRunner-II CPLDs.
</li></ul>
<p>We mapped the BUTTON input market to pin 18. The LED output marker connects to pin 39 (D1), and LED_INV connects to pin 38 (D2).
