摘要： The on-chip power supply noise sensor detects high frequency overshoots and undershoots of the power supply voltage. By creating two identical current sources and attaching a time constant circuit to only one, the high frequency transient behavior differs while the low frequency behavior is equivalent. By comparing these currents, the magnitude of very high frequency power supply noise can be sensed and used to either set latches or add to a digital counter. This has the advantage of directly sensing the power supply noise in a manner that does not require calibration. Also, since the sensor requires only one power supply, it can be used anywhere on a chip. Finally, it filters out any lower frequency noise that is not interesting to the circuit designer and can be tuned to detect down to whatever frequency is needed.

摘要： Self-synchronizing techniques for checking the accuracy of a pseudorandom bit sequence (PRBS) are provided. The PRBS being checked may be generated by a device (e.g., a device under test) in response to a PRBS received by the device (e.g., from a PRBS generator). In an aspect of the invention, a PRBS checking technique includes the following steps/operations. For a given clock cycle, the presence of an error bit in the PRBS generated by the device is detected. The error bit represents a mismatch between the PRBS input to the device and the PRBS output from the device. Then, propagation of the error bit is prohibited for subsequent clock cycles. The prohibition step/operation may serve to avoid multiple errors being counted for a single error occurrence and/or masking errors in the PRBS output by the device.
