  • Patent number: 8072242
    Abstract: Embodiments provide input/output devices having programmable logic that is programmable to operate input/output devices in one of two drive modes. In various embodiments, to operate an input/output device in a first drive mode, logic circuitry is programmable to couple a reference voltage to a gate of a transistor element of an output driver. In various embodiments, to operate an input/output device in a second drive mode, the logic circuitry is programmable to couple a bias voltage to the gate of the transistor element of the output driver. In various embodiments, the logic circuitry may also be programmable to couple one of a plurality of data inputs to the output driver to operate an input/output device in either a single-ended mode or a differential mode.

  • Patent number: 8003906
    Abstract: Embodiments of crossbar devices constructed with Micro-Electro-Mechanical Systems (MEMS) switches are disclosed herein. A crossbar device may comprise m input terminals, n output terminals, n control lines and m×n MEMS switches coupled to the n control lines to selectively couple the m input terminals to the n output terminal. Each of the MEMS switches may comprise a contact node coupled to one of the m input terminals, a cantilever coupled to one of the n output terminals, a control node coupled to one of the n control lines to electrostatically control the cantilever to contact the contact node or be away from the contact node using electrostatic attractive or repulsive force respectively. The cantilever and the contact node are configured to remain in contact by molecular adhesion force, after the cantilever has been electrostatically controlled to contact the contact node, and the electrostatic attractive force has been removed. Other embodiments may be described and claimed.

  • Publication number: 20100040122
    Abstract: Embodiments provide methods, systems, and apparatuses including combinatorial or reconfigurable circuitry having input/output (I/O) circuitry with an I/O terminal and an input buffer. The I/O terminal receives a receive signal at a receive signal level that was transmitted from another integrated circuit at a transmitted signal level which is either a first or a second different signal level. The input buffer compares the receive signal to one or more reference signals to generate an input signal corresponding to the transmitted signal level based at least in part on the result of the comparison, even if the receive signal is received at a third signal level in between the first and the second signal level.

  • Patent number: 6934674
    Abstract: A method and apparatus for clock generation and distribution in an emulation system is described. The present invention provides a method and apparatus for generating a derived clock signal with a circuit having a look up table. A counter circuit counts clock cycles and provides an index into the look up table. A frequency divider circuit may be used between the counter circuit and a base clock signal to provide an intermediate clock signal with a frequency that is less than the frequency of the base clock signal. In one embodiment, a selection circuit is provided to select between the base clock signal and an external clock signal.

  • Publication number: 20040178820
    Abstract: A number of enhanced logic elements (LEs) are provided to form a FPGA. Each enhanced LE comprises a multiple input-single output truth table, and a complementary pair of master-slave latches having a data, a set and a reset input. Each enhanced LE further comprises a plurality of multiplexers and buffers, and control logic. Additionally, the improved FPGA further comprises a network of crossbars, a context bus, a scan register, and a plurality of trigger circuitry. As a result, each LE may be individually initialized, its signal state frozen momentarily, the frozen state be read, trace data be output, and trigger inputs be conditionally generated. Furthermore, the enhanced LEs may be used for “level sensitive” as well as “edge sensitive” circuit design emulations.

  • Patent number: 6717433
    Abstract: A number of enhanced logic elements (LEs) are provided to form a reconfigurable integrated circuit (IC). Each enhanced LE comprises a multiple input-single output truth table, and a complementary pair of master-slave latches having a data, a set and a reset input. Each enhanced LE further comprises a plurality of multiplexers and buffers, and control logic. Additionally, the improved IC may further comprises a scalable network of crossbars, a context bus, a scan register, and/or a plurality of trigger circuitry. As a result, each LE may be individually initialized, its signal state frozen momentarily, the frozen state be read, trace data be output, and trigger inputs be conditionally generated, making the IC particularly suitable for circuit design emulation. Furthermore, the enhanced LEs may be used for “level sensitive” as well as “edge sensitive” circuit design emulations.
