Program-based stimulus
ConceptA program-based stimulus is a form of verification stimulus for simulation-based processor verification in which the stimulus is represented as a program loaded directly into the processor's program memory, rather than as raw bit vectors applied to input ports.

Definition
In simulation-based processor verification, a program-based stimulus is a stimulus represented by a program that is loaded directly into the processor's program memory. This contrasts with another stimulus form in which bit vectors are applied directly to the processor's input ports.
