  • Patent number: 7924845
    Abstract: Message send and receive blocks are provided to emulation ICs and reconfigurable interconnect ICs of an emulation system to reduce the multiplexed transfer latency of critical emulation signals. Each of a corresponding pair of a message send block and a message receive block is provided with a signal state value inclusion schedule to control operation of the message send and receive blocks. The signal state inclusion schedule calls for some signals within a message to be sent more often than other signals within the message. In some embodiments a parity value is implemented as part the message and included in the signal state inclusion schedule.
