A Complex Programmable Logic Device (CPLD) is a rewritable logic device with a relatively complex circuit structure.
CPLDs have made the development of products easier and less expensive than ever before.
CPLDs are widely used in the control boards of various consumer and industrial products, such as:
CPLDs are used in control circuits, particularly for the management of power circuits. They are often responsible for managing the order in which power is applied to circuits, voltage selection circuits, and other functions.
A CPLD consists of a block in which multiple programmable logic circuits are integrated and a wiring area that connects the different blocks. The block consists of three macrocells with AND-OR gate structures, a D-type flip-flop to hold one bit of information as either 0 or 1, and I/O pins for input and output.
The macrocell inputs digital signals from the Input pin and outputs signals to the Output pin with user-programmed logic circuitry. Internal primary data is stored in flip-flops.
The Routing Area is the connection between blocks and output data through one or more blocks.
Field-Programmable Gate Arrays (FPGAs) are similar to CPLDs in that they use volatile memory, which means that circuit data is lost when power is removed.
CPLDs, on the other hand, use nonvolatile memory, such as EEPROM or flash memory, which retain circuit data. There is also a difference in scale.
FPGAs have tens of thousands of gates, while CPLDs have only a few thousand. Therefore, CPLDs are used to provide design data to FPGAs when power is turned on, while FPGAs are used to perform large-scale logic circuitry.
Additionally, latency varies depending on where the logic blocks are located, making it difficult for the FPGA to predict. In contrast, latency is easier for CPLDs to predict because the number of macrocells to be routed through them is fixed.
CPLDs were developed to replace TTL and CMOS logic devices about 30 years ago. At that time, circuits were constructed by combining general-purpose logic ICs with only NOT and AND functions.
The 7400 series from Texas Instruments (TI) is well known, but it is said that engineers at that time had to memorize hundreds of devices. The problem was that as circuits became more complex, dozens to hundreds of general-purpose logic ICs were required, resulting in huge board sizes.
As transistor miniaturization progressed, it became possible to realize thousands or tens of thousands of general-purpose logic ICs in a few LSIs, which accelerated the development of CPLDs.
The development process for CPLD design is categorized into the following steps: logic design, logic synthesis, place and route, timing verification, and programming.
