    摘要: A system for implementing a chip lockout protection scheme for an IC device includes an on-chip password register that stores a password externally input by a user; an on-chip security block that generates a chip unlock signal, depending on whether the externally input password matches a correct password; an on-chip false data generator; an input protection scheme configured to gate the external data inputs to functional chip circuitry upon entry of the correct password; and an output protection scheme in communication configured to steer true chip data to external outputs of the IC device upon entry of the correct password, and to steer false data generated by the false data generator to the external outputs upon entry of an incorrect password. The false generated by the false data generator is deterministic and based upon external data inputs, thereby obfuscating whether or not the correct password has been entered.

    摘要: A design structure for a clock system for a plurality of functional blocks designed using a method of reducing peak power that utilizes connectivity and/or timing information among a plurality of design partitions of an integrated circuit system to create a clock system that reduces peak power consumption across the system. The method used to create the design structure includes sorting the design partitions according to a connectivity model, a timing model, or both, and assigning interleaved clock signals as a function of the design partition ordering. The clock system is created as a function of the interleaved clock signals.

    摘要: A system and method for verifying system-on-chip interconnect includes a first linear feedback shift register coupled to an output interface of a first system-on-chip component, a second linear feedback shift register instantiated in a second system-on-chip component, and a comparator coupled to the second linear feedback shift register and the input interface of the second system-on-chip. Another method for verifying includes generating a pseudo-random number sequence with the first linear feedback shift register and the second linear feedback shift register using an identical first initial state, and comparing an output of the first linear feedback shift register with an output of the second linear feedback shift register and reporting a miss-compare.
