SOFT ERROR AND TRANSIENT ERROR DETECTION DEVICE AND METHODS THEREFOR

摘要

A clock signal is received at a clock node of a latch module, and a data signal is received at a data node of the latch module. The data signal including information to be latched at a first latch of the latch module and at a second latch of the latch module. A first representation of the data signal to a first data node of the first latch is delayed relative to a second representation of the data signal to a corresponding first data node of the second latch to obtain a first timing requirement between the data signal and the clock signal relative to the first latch that is substantially different than a second timing requirement. An error signal is generated in response to different data being latched at the first latch than at the second latch.
