摘要： Driving multiple consecutive bits having a same logic value in a serial data stream involves driving a first bit of the multiple consecutive bits in the serial data stream at an initial voltage level, and driving at least two additional bits of the multiple consecutive bits in the serial data stream at voltage levels stepped down from the initial voltage level.

摘要： A method, system, and a computer usable program code for reducing the effects of intersymbol interference in a high speed data transmission using various steps. First, a training sequence is established between a transmitter operably connected by a conductor to a receiver. Data is analyzed at the receiver. Transition bits following a stable data stream are skewed by the transmitter. When data is received at the receiver, the variable transition time for the transition bits is adjusted by the transmitter to optimize timing and reduce timing effects of intersymbol interference.

摘要： A method, system, and computer usable program code for increasing drive strength using various steps. First, a data signal is received at a receiving device. The receiving device determines whether the data is successfully received once the data signal is received at the receiving device. If the receiving device determines that the data signal is unsuccessfully received, the receiving device requests an increase in a signal amplitude of the data signal transmitted by a transmitting device that sent the data signal for increasing the drive strength.

摘要： A system, apparatus and method for testing and optimizing an electrical device using a simultaneous display of both a signal's eye diagram and total jitter profile are described. In one embodiment of the invention, a data capture module capable of obtaining and separating the total jitter present in a signal into deterministic and random jitter, as well as other eye diagram information, is coupled to the electrical device and one or more display devices. These one or more display devices provide a user a simultaneous visual display of both random jitter and an eye diagram. This simultaneous display allows a user to test and optimize the electrical device without having to attach and detach the electrical device to multiple measuring devices.

摘要： Methods and structures within a SAS domain for automated tuning performance of a coupled pair of transceivers. In one aspect hereof, control registers of a transmitting transceiver coupled to a receiving transceiver are adjusted to a plurality of distinct combinations of settings. For each distinct setting, a test pattern may be transmitted from the transmitting transceiver to the receiving transceiver. Status registers of the transmitting transceiver and of the receiving transceiver may be read to identify errors in the transmission. Identified errors are counted for each for distinct setting of the control registers to determine a preferred setting to best tune operation of the transceiver pair. The testing may be performed by any SAS initiator device or SAS expander acting as an initiator and may be performed on any coupled pair of transceiver in the SAS domain.

摘要： Methods and systems are provided for thermal self-monitoring of integrated circuits. Temperature is sensed, digitized, encoded, and compared to one or more threshold values by circuits added within an integrated circuit. A signal produced by a thermal diode within an integrated circuit is applied to an analog to digital converter and may be compared to one or more threshold values to produce a digital over temperature condition signal. An appropriate cooling action may be initiated by processing of the digital signal so produced. Also provided are methods and systems to alter the range and resolution of the temperature threshold comparisons.

摘要： Disclosed is a method and apparatus for providing a universal SCSI bus interface in which bus performance is not degraded, and the analyzer is not negatively influenced by post processing while maintaining the ability to filter and store data using any of a number of generic logic analyzers. The SCSI bus interface does not rely on a specific clock speed and maintains the ability to view both raw data and protocol errors. The universal SCSI bus interface embodiments described herein produce stable clock signals for use by an analyzer in a form that is phase and frequency stabilized with the SCSI bus clock. This allows data sampling to mimic the performance characteristics of a device attached to the SCSI bus thereby minimizing sampling error.

摘要： A system and method for testing a device with multiple interfaces by generating a predetermined data pattern within the device, transmitting the pattern to a test analyzer, generating a second predetermined data pattern within the test analyzer, and simultaneously transmitting the second test pattern to the device where the second test pattern is verified. The first and second test patterns may be the same or different, depending on the application. Further, the transmit and receive paths may be tested separately and independently in addition to simultaneously.

摘要： Disclosed is a process for controlling the expander cores of a dual expander using a single test port, such as a J-tag port. Access to and control of each expander core is accomplished by placing one of the cores in a bypass mode and accessing and controlling the other core through data supplied serially through the J-tag port.
