What you will need to design with PLDs A few pieces of hardware are required in order to work with Programmable Logic Devices. The most expensive of these is the device programmer. For the professional engineer Contact details of suppliers of inexpensive PLD programmers can be found in the back of many electrical engineering journals or magazines.
Most manufacturers offer.
Larger, more expensive universal programmers are capable of programming a wide range of devices and possess the ability to run functional test vectors to ensure correct operation. Professional engineers generally have access to variable power supplies, function generators and oscilloscopes. Engineer working with PLDs To obtain PLDs contact your local device vendor, or visit their web site and request sample devices. Most silicon vendors will be happy to provide a few of their devices if they believe that you may purchase large quantities in the future.
