20150095388 | Configurable Multiply-Accumulate - Field programmable gate arrays (FPGA) contain, in addition to random logic, also other components, such as processing units, multiply-accumulate (MAC) units, analog circuits, and other elements, configurable with respect of the random logic, to enhance the capabilities of the FPGA. A circuit for a filed configurable MAC unit is provided to allow various configurations of ADD, SUBTRACT, MULTIPLY and SHIFT functions. Optionally, registered input and registered output support a multi-cycle path.

20150058669 | Method and Apparatus for Error Management of an Integrated Circuit System - An apparatus and method for error management in an integrated circuit system are presented. An error management unit (EMU) apparatus manages critical and non-critical errors that may be masked or non-masked. An EMU includes an EMU state machine, having a BOOT state, a CONFIG state, a FUNCT state, a WARNING state and an ERROR state. The method discloses transitions in the EMU state machine. While in the ERROR state an error reaction may be applied. The objective of the error reaction is to recover errors by software and hardware means. The EMU may further appropriately alert the system while in ERROR state and therefore be used as a safety mechanism permitting to collect error signals issued by fault detector units and can further cause action on faulty units for recovery purposes. | 02-26-2015 |
20140365814 | IO Pad Circuitry with Safety Monitoring and Control for Integrated Circuits - An input/output (IO) pad circuitry for integrated circuits (ICs) that is equipped with safety monitoring and control circuits to ensure that signals provided to/from the IO pad behave correctly. The IO pad circuitry allows monitoring of the IO pad signals, the detection of an undesired behavior, e.g., a wrong signal level or a wrong waveform. Furthermore, depending on a selected safety mode, a correction of the IO pad signals by overriding the monitored signal is further achieved. When in full safe mode, signals are provided as required, while in a partial safe mode only certain signals are provided depending on the status. A grouped safe mode allows providing a safe status to a group of IO pads using a single control. A monitoring circuitry between a plurality of input signals to an IC pad is also provided. | 12-11-2014 |
20140217406 | Apparatus and Method for Non-Intrusive Random Memory Failure Emulation Within an Integrated Circuit - The system and methods allow for emulation of random hardware failure of an internal embedded memory array of an integrated circuit (IC) device. Emulation of potential defects is performed in order to evaluate the behavior of the rest of the design. This non-intrusive emulation is performed in a pseudo-functional mode in order to evaluate the behavior of one or more memory cores in their standard functional mode. The solution enables the creation of failures and tracking both the detection of the failures and the time required time for detection. Specifically, the emulation of an internal memory array with respect of random failures and the associated diagnostic mechanism ensures that detection and correction mechanisms work as expected. A typical non-limiting use case is to ensure that safety control logic of an IC behaves as expected in cases of data corruption within an embedded memory core. | 08-07-2014 |
20140201583 | System and Method For Non-Intrusive Random Failure Emulation Within an Integrated Circuit - The apparatus and methods allow random hardware failure emulation of an integrated circuit (IC) by emulation of potential defects to enable behavior evaluation of the rest of the design in such situation. This emulation can non-intrusively address multiple points of failure. The emulation is performed in a pseudo-functional mode in order to evaluate the IC behavior in its standard functional mode. The system allows creation of a failure, and tracking both the detection of this failure and the required time for this detection. The system further allows generation of a failure in different points of the IC, on a single or multipoint failure approaches. Failure detection and correction mechanisms for a product life cycle are therefore provided. In an embodiment the system checks the conformity of the safety function of an IC, and makes sure the safety control logic behaves as expected in case of data corruption in any register. | 07-17-2014 |
