Abstract: A system for presenting serial drive signals for effecting communication of parallel data signals includes: a controller; a serializer coupled with the controller; and a tri-state logic device coupled with the serializer. The controller provides parallel logic state signals to the serializer. The serializer treats the parallel data signals to present a serial data signal representing the parallel data signals at a first output locus, and treats the parallel logic state signals to present a serial logic state signal representing the parallel logic state signals at a second output locus. The tri-state logic device receives the serial data signal and the serial logic state signal for logical evaluation. The tri-state logic device presents the serial drive signals at a third output locus. Each respective drive signal has a respective drive state. Each respective drive state is determined by the logical evaluation.

Abstract: A computer program (100, 200) encoded in a computer-programmable medium, and for causing a computer to perform circuit design. The code causes the computer to perform a set of steps. The steps comprise describing a first set of circuitry and describing a second set of circuitry. The steps also comprise describing a digital signal for passing from the first set of circuitry to the second set of circuitry and detecting (230) transitions of the digital signal with respect to a timing constraint (240) of at least a portion of the second set of circuitry. Lastly, the steps comprise, responsive to detecting metastability with respect to timing of a transition of the digital signal relative to the timing constraint of at least a portion of the second set of circuitry, forcing (160) the digital signal to a random value and passing the random value to the second set of circuitry.

Abstract: An electronic device (10). The device comprises a memory structure (12) structure comprising an integer M of word storage locations. The device further comprises a shift register (SRRD; SRWT) for storing a sequence of bits. The sequence in the shift register comprises a number of bits equal to a ratio of 1/R1 times the integer M. The device further comprises circuitry (16) for providing a clock cycle to the shift register for selected data operations with respect to any of the word storage locations. The selected data operations are a data read or a data write. In response to each clock cycle, received from the circuitry for providing the clock cycle, the shift register shifts the sequence. Further, one bit in the sequence corresponds to an indication of one of the memory word storage locations from which a word will be read or into which a word will be written.
