Low-cost programmable logic: How low should you go?

摘要

1. Low-cost PLDs are of greatest interest if gate-count and performance needs are moderate and if you don't need or want to bother with low operating voltages. 2. Do a little math before deciding that a cost-focused PLD or FPCA is a better choice than a more expensive alternative with premium features. PLDs' and FPGAs' integration of memory, digital delay-locked loops, or PLLs and other circuits may result in a lower system cost. 3. Devices with premium price tags also have more robust logic and routing resources, reducing the budget-busting time and effort you need to squeeze your design onto the chips. 4. Verify with your salesperson availability and pricing claims.
