Programmable Logic Device - Technical MCQs

Q1:

A unit of logic in an FPGA that is made up of multiple smaller logic modules and a local programmer interconnect that is used to connect internal logic modules is called a ________.

A bed-of-nails

B boundary scan

C CLB

D CPLD

ANS:C - CLB

A configurable logic block (CLB) is the basic repeating logic resource on an FPGA. When linked together by routing resources, the components in CLBs execute complex logic functions, implement memory functions, and synchronize code on the FPGA.
