In a preferred embodiment of the invention, a mirror compiler is provided for each protected device or circuit resulting in a program that is embedded into the protected device's source code. The mirror compiler can be configured to have multiple selectable compilation parameters offering the programmer flexible options for mirrored power cancellations. In the preferred embodiment, the mirror compiler comprises a digital-to-analog converter and a digital-to-analog load to sink current. These elements serve to define a complement of the normal (i.e., unprotected) programmed device's output current. The digital-to-analog load currents are output and thus act to cancel the expected variations in the currents of the protected programmed device.
