Patent ID: 8233551

Claim:
A system comprising: a first agent including transmitter logic to transmit a training pattern at a first differential voltage; a second agent coupled to the first agent through a link, the second agent including receiving logic to receive the training pattern, error logic to determine if an error is detected in the training pattern, and transmitting logic to transmit a no-error message to the first agent to indicate no error was detected during the training pattern in response to the error logic determining no error is detected in the training pattern; wherein the transmitter logic included in the first agent is further to scale the first differential voltage by a value greater than one to a scaled differential voltage in response to the first agent receiving the no-error message to indicate no error was detected during a test pattern, wherein a length of the training pattern is to be associated with a first sigma value of a normal curve distribution, and wherein the first agent is further to scale the first differential voltage by a value greater than one to a scaled differential voltage comprises the first agent is further to scale the first differential voltage by ratio of a target sigma value of the normal curve distribution and the first sigma value, which is greater than one, to a scaled differential voltage.
