DETERMINING A VOLTAGE AND/OR FREQUENCY FOR A PERFORMANCE MODE

Abstract:

According to certain aspects, a method includes receiving an input test signal at a test input, receiving an event signal, and passing the input test signal to a test output or blocking the input test signal from the test output based on the event signal. In certain aspects, the event signal indicates an occurrence of an event in a circuit block (e.g., a memory, a processor, or another type of circuit block). The event may include a precharge operation, opening of input latches, reset of a self-time loop, arrival of a data value at a flop in a signal path, an interrupt signal indicating an error or failure in the circuit block, or another type of event.
