As CPLDs and FPGAs become more advanced the differences between the two device types will continue to blur.
<p>

While this trend may appear to make the two types more difficult to keep apart, the architectural advantage of CPLDs combining low cost, non-volatile configuration, and macro cells with predictable timing characteristics will likely be sufficient to maintain a product differentiation for the foreseeable future.

What kinds of programmable logic devices are available today?
How are they different from one another?
<p>
There are a few major programmable logic architecture available
today. Each architecture typically has vendor-specific sub-variants
within each type. The major types include:
<ul>
<li>EPLD: Erasable Programmable Logic Device
<li>SPLD: Simple Programmable Logic Device
<li>CPLD: Complex Programmable Logic Devices
<li>FPGA: Field Programmable Gate Arrays
<li>FPIC: Field Programmable InterConnect 
<li>FPOA: (field programmable object array).
</ul>
