Testing microelectronic devices using electro-optic modulator probes is disclosed. In one aspect, a testing apparatus may include an electrical signaling medium to exchange electrical signals with a microelectronic device. The testing apparatus may include an electro-optic modulator probe to provide optical signals that are modulated by the electrical signals. An optoelectronic transducer may be included to convert the modulated optical signals to modulated electrical signals. The testing apparatus may further include a logic analyzer module to receive and analyze the modulated electrical signals. Other testing apparatus are disclosed, as well as systems incorporating such apparatus, and various methods of testing microelectronic devices.

In one embodiment, the present invention includes a method for receiving an error correction code for information from a first port of a first agent and receiving the information from a second port of the first agent by probing a first link under test that couples the first agent and a second agent. The code may be used to validate the information, e.g., in a probe receiver during test or debug operations. Other embodiments are described and claimed.
摘要:
Transmit equalization over high speed digital communication paths may be compensated in a receiver for a probe on that path. In one example, a probe input provides a signal from an electronic communications path, the signal having been processed by a transmit equalizer. A filter circuit processes the signal to compensate for the transmit equalizer, and a decoder decodes the processed signal and produces an output for use by test equipment.
