Circuit underutilization
Not using the area or components of an integrated circuit to full efficiency / From Wikipedia, the free encyclopedia
Circuit underutilization also chip underutilization, programmable circuit underutilization, gate underutilization, logic block underutilization refers to a physical incomplete utility of semiconductor grade silicon on a standardized mass-produced circuit programmable chip, such as a gate array type ASIC, an FPGA, or a CPLD.
Not to be confused with Circuit minimization for Boolean functions, which is logical optimization rather than physical.
