Abstract: Apparatus for storing all logic simulation signal values generated by a logic simulator during a simulation run is provided. The apparatus includes a runtime array for storing a plurality of signal values for each time instance in a predetermined time period, and a checkpoint cache for selectively storing the plurality of signal values stored in the runtime array at selected time instances. A hyper-checkpoint array is further provided to checkpoint the signal values in the checkpoint cache. In addition, the time instances and values of memory writes are also checkpointed. A user may retrieve the value of any signal values generated during the simulation run and may additionally rewind the simulator to a user-specified time in the simulation run.

Abstract: Identifying relationships among records includes accessing a search record and corpus records. The search record comprises search tokens, where a search token is associated with a search token count. A corpus record comprises corpus tokens, where a corpus token is associated with a corpus token count. The following are repeated for each of at least a subset of the search tokens: identifying corpus tokens corresponding to the search token, and comparing the search token with the identified corpus tokens to yield comparisons. A relationship between the search record and at least one corpus record is determined in accordance with the comparisons.

Abstract: Performing operations using quantum correlithm objects includes establishing real states, where each real state comprises an element of a real space, and encoding the real states as quantum objects representing a correlithm object. The correlithm object is projected to the real space using a measurement basis, and measurement values corresponding to the measurement basis are determined. The projected correlithm object is retrieved according to the measurement values.

Abstract: Encoding bits includes receiving a bit set to encode. An encoding lookup table associates correlithm objects of a space with bit sets. The space refers to an N-dimensional space, a correlithm object refers to a point of the space. The correlithm object corresponding to the received bit set is identified. The received bit set is encoded as the identified correlithm object. The identified correlithm object is imposed to encode the received bit set and subsequently decoded with table lookup using the reverse process.

Abstract: A virtual field programmable gate array device (20) includes a plurality of processors (22), each containing a central processing unit (24), memory (34), and a network interface (26). Each processor (22) may be programmed to emulate a multiple number of gates of a conventional field programmable gate array device. Each processor (22) is part of a network array to allow for information transfer between and among each processor (22). Information transfer is accomplished through the use of delivery units (50) that identify the routing vector for the information to an appropriate processor (22).
