20130132453 | GENERATING UNIQUE RANDOM NUMBERS FOR MULTIPLE INSTANTIATIONS - In a first embodiment of the present invention, a method for generating a random number for an instance of a hardware description language definition is provided, the method comprising: generating a unique signature for the instance; applying a message digest generation process on the unique signature to arrive at a message digest having a fixed length; and applying a random number generation process on the message digest. | 05-23-2013 |

20130191427 | PSEUDO-NOISE GENERATOR - The present invention relates to a pseudo-noise generator comprising a plurality of pseudo-random number generators and an averaging unit. The averaging unit is arranged to receive a plurality of pseudo-random numbers from the plurality of pseudo-random number generators, calculate a mean value of the plurality of pseudo-random numbers, and output said mean value as a digital pseudo-noise signal. | 07-25-2013 |
