Sr. No.	FPGA	CPLD
1	It is field programmable gate array.	It is complex programmable logic device.
2	Capacity is defined in terms of number of gates available.	Capacity is defined in terms of number of macro-cells available.
3	FPGA consumes less power than CPLD.	CPLD consumes more power than FPGA devices.
4	Number of input and output pins on FPGA are less than CPLD.	Number of input and output pins on CPLD are high.
5	FPGA are suitable for designs with large number of simple blocks with few number of inputs.	CPLD are ideal for complex blocks with large number of inputs.
6	FPGA based designs require more board space and layout complexity is more.	CPLD based designs need less board space and less board layout complexity.
7	It is difficult to predict the speed performance of design.	It is easier to predict the speed performance of design.
8	FPGA are available in wide density range.	CPLD contain fewer registers but have better performance.
