Abstract
The present invention teaches a method for designing an integrated circuit. The design of the integrated circuit is replicated a number of times. The number of times must be odd. The input signals to the original module are also replicated. The replicated modules are configured to respectively receive the replicated input signals. A number of exclusive or gates is provided. The exclusive or gates receive the output signals from the replicated modules. The output signals from the replicated modules are compared to the output signals from the original module. The method is applicable to a bi-directional integrated circuit. Embodiments include the software to replicate the design. Another embodiment includes a computer system for replicating the design. Also, integrated circuits designed by the method described are included within the scope of the disclosure. Another embodiment includes designs produced by the method.
