design changes into the CPLD development tool, and re-implement and test the
design immediately.
Lower Development Costs: CPLDs offer very low development costs. Because
CPLDs are re-programmable, you can easily and very inexpensively change
your designs. This allows you to optimize your designs and continue to add new
features to enhance your products. CPLD development tools are relatively
inexpensive (or in the case of Xilinx, free). Traditionally, designers have had to face
large cost penalties such as re-work, scrap, and development time. With CPLDs, you
have flexible solutions, thus avoiding many traditional design pitfalls.
More Product Revenue: CPLDs offer very short development cycles, which means
your products get to market quicker and begin generating revenue sooner. Because
CPLDs are re-programmable, products can be easily modified using ISP over the
Internet. This in turn allows you to easily introduce additional features and quickly
generate new revenue. (This also results in an expanded time for revenue). Thousands
of designers are already using CPLDs to get to market quicker and stay in the market
longer by continuing to enhance their products even after they have been introduced
into the field. CPLDs decrease TTM and extend TIM.
Reduced Board Area: CPLDs offer a high level of integration (that is, a large number
of system gates per area) and are available in very small form factor packages. This
provides the perfect solution for designers whose products which must fit into
small enclosures or who have a limited amount of circuit board space to implement
the logic design. Xilinx CoolRunner CPLDs are available in the latest chip scale
packages. For example, the CP56 CPLD has a pin pitch of 0.5 mm and is a mere 6 x 6
mm in size, making it ideal for small, low-power end products. The CoolRunner-II
CPLDs are also available in the QF (quad flat no-lead) packages, giving them the
smallest form factor available in the industry. The QF32 is just 5 x 5 mm in size.
Cost of Ownership: Cost of Ownership can be defined as the amount it costs to
maintain, fix, or warranty a product. For instance, if a design change requiring
hardware rework must be made to a few prototypes, the cost might be relatively
small. However, as the number of units that must be changed increases, the cost
can become enormous. Because
hardware rework, it costs much less to make changes to designs implemented using
them. Therefore cost of ownership is dramatically reduced.
Don't forget that the ease or difficulty of design changes can also affect opportunity
costs. Engineers who spend time fixing old designs could be working on introducing
new products and features ahead of the competition.
There are also costs associated with inventory and reliability. PLDs can reduce
inventory costs by replacing standard discrete logic devices. Standard logic has a
predefined function. In a typical design, lots of different types have to be purchased
and stocked. If the design is changed, there may be excess stock of superfluous
devices. This issue can be alleviated by using PLDs. You only need to stock one device;
