Abstract
Secure initialization of the state of an electronic circuit. A processor determines the trusted state of one or more architecture state registers of an intellectual property core. The processor clears entries in a memory of the intellectual property core. The processor verifies that state machines, included in execution logic of the intellectual property core, have not generated output.
