Abstract: A digital on-die-test engine (OTE) generates stimuli signals for an analog/RF circuit, where the OTE is embedded within the circuitry. The stimuli signals are injected into the circuit, feed through the circuit, and are received back into the OTE for analysis. The OTE includes an input subsystem to receive signals from various locations throughout the circuit. The received signals are sub-sampled before being tested. The OTE includes memory-aware and memory-less algorithms for testing the signals. The OTE is capable of changing the configuration of the circuit, where needed, following the tests.

Abstract: Briefly, in accordance with one or more embodiments, a radio device comprises an analog front end comprising a radio to transmit and/or receive radio-frequency signals, and a programmable engine coupled to the analog front end. The programmable engine is capable of being programmed to perform one or more tests on the analog front end and includes a reconfigurable data path reconfigurable by the programmable engine to perform one or more tests on the analog front end.

Abstract: Techniques for a programmable engine to provide security mechanisms protecting information which is in support of testing and/or calibration a radio front end. In an embodiment, test/calibration information is to be communicated to, from or within the programmable engine for processing by a particular resource of the programmable engine. In another embodiment, test/calibration is exchanged along a dedicated hardware data path between a security module of the programmable engine and an execution module of the programmable engine, wherein any data exchanged in the dedicated hardware data path is only accessible from the dedicated hardware data path via one or both of the security module and the execution module.
