  • Patent number: 8611406
    Abstract: Communication system optimization using a soft receiver masking technique is disclosed. For example, a method for testing a communication device comprises obtaining a software representation of a receiver portion of a given communication device. A data signal received from a transmitter through a given link channel is then processed, wherein the processing step is performed using the software representation of the receiver portion of the communication device. An output signal is caused to be generated by the software representation of the receiver portion. An eye mask test is then applied to the output signal. Based on a result of the eye mask test, one or more parameters of the transmitter may be adjusted.

  • Patent number: 8612632
    Abstract: Methods and structures for validating tag information received in SAS frames by any of a plurality of ports comprising a SAS wide port. Each port may have a dedicated transport layer processing element. A tag information table is shared by all of the one or more transport layer processing elements. The tag information table is used to store information regarding a particular tag value being valid for use with a particular device and is updated when the particular tag value is no longer valid for use with the particular device. The information is initially stored in response to transmission of a frame that first uses the particular tag value with the particular device. The tag information table is updated to indicate the particular tag value is no longer valid upon receipt of an appropriate SAS frame or by a processing element external to the one or more transport layer processing elements.

  • Patent number: 8607180
    Abstract: An integrated circuit (IC) or a block of an IC is routed. The signals of the netlist to be routed are grouped according the signal properties. A signal property may be the time or clock used to initiate the switching of the signal. The signals of each group are routed successively. This causes the signals of later groups to be routed between the signals of previous groups thereby providing shielding between signals lines of the same group.

  • Patent number: 8605847
    Abstract: In described embodiments, a transceiver includes a clock and data recovery module (CDR) with an eye monitor and a cycle slip monitor. The cycle slip detector monitors a CDR lock condition, which might be through detection of slips in sampling and/or transition timing detection. The cycle slip detector provides a check point to sense system divergence, allowing for a mechanism to recover CDR lock. In addition, when the CDR is out-of-lock, the various parameters that are adaptively set (e.g., equalizer parameters) might be invalid during system divergence. Consequently, these parameters might be declared invalid by the system and not used.
