1. A method to detect a malware of a field programmable gate array (FPGA) through voltage measurements of the FPGA, the method comprising: initiating a scan during an inactivity of the FPGA for the malware; measuring voltages of distinct areas that include at least one from a set of: an existing sensor within the FPGA or a new sensor positioned adjacent to the FPGA; creating a power map from the voltages; executing the scan by comparing the power map to an expected activity information associated with the FPGA; and evaluating whether a power consumption by a coprocessor of the FPGA exceeds a predetermined threshold, wherein the predetermined threshold is retrieved from a virus data store.
