    Abstract: According to an embodiment described herein, a method for testing a memory includes receiving an address and a start signal at a memory, and generating a first detector pulse at a test circuit in response to the start signal. The first detector pulse has a leading edge and a trailing edge. A data transition of a bit associated with the address is detected. The bit is a functional bit. The method further includes determining whether the bit is a weak bit by determining whether the data transition occurred after the trailing edge.

    Abstract: An integrated circuit includes a continuous time delta sigma analog-to-digital converter (CTDS ADC) and a test circuit for testing the CTDS ADC. The test circuit converts multi-bit digital reference data to a single-bit digital stream. The test circuit then passes the single-bit digital stream to a finite impulse response digital-to-analog converter (FIR DAC). The FIR DAC converts the single-bit digital stream to an analog test signal. The analog test signal is then passed to the CTDS ADC. The CTDS ADC converts the analog test signal to digital test data. The test circuit analyzes the digital test data to determine the accuracy of the CTDS ADC.

    Abstract: Disclosed is a system and method for providing a critical path replica system in a circuit. A critical path replica system is created by determining a critical path in a circuit, generating a critical path replica circuit, generating a circuit blueprint, and creating the blueprinted circuit. The circuit comprises a functional logic module having functional logic elements and replica logic modules having logic elements. Each logic element is configured to replicate one or more of the functional logic elements and process a test signal. A replica error detection module analyzes the processed signal to determine whether a timing violation has occurred. In some embodiments, the replica logic module further comprises one or more load modules. A replica controller may modify operation of the circuit based on reported errors. A replica mode select module sets the replica logic module to an aging test mode or a timing sensor mode.

    Abstract: A continuous time, sigma-delta analog-to-digital converter circuit includes a sigma-delta modulator circuit configured to receive an analog input signal. A single bit quantizer of the modulator generates a digital output signal at a sampling frequency. A data storage circuit stores bits of the digital output signal and digital-to-analog converter (DAC) elements are actuated in response to the stored bits to generate an analog feedback signal for comparison to the analog input signal. A filter circuit includes polyphase signal processing paths and a summation circuit configured to sum outputs from the polyphase signal processing paths to generate a converted output signal. A fan out circuit selectively applies the stored bits from the data storage circuit to inputs of the polyphase signal processing paths of the filter circuit.
