Uniform Redundant Codes Formation Principles for the Self-Checking Combinational Devices Synthesis Based on Structures Data

The organizing task of the automation and computer technology combinational devices testing with the diagnostic tools synthesized using redundant coding is considered. In comparison with known approaches that involve the use of binary uniform codes, this article proposes a method for building a uniform separable code. The proposed code considers the combinational device structural features. This method allows to "lay" in the code under construction information about possible errors at the circuit outputs. This allows them to be considered when synthesizing the check circuit. At the same time, at the task setting stage, it is required to specify the fault model, relative to which the code with error detection will be built. In comparison with the already known redundant code, the proposed method makes it possible to consider their structure's individual features. The use of such an approach to the selfachecking combinational device's organization with an unchangeable structure expands the number of ways to construct them, in comparison with the previously known duplication and circuit outputs groups control using by codes with special diagnostic properties.
Keywords: selfachecking combinational circuit, uniform separable binary code, error detection at the combinational circuit's outputs, "under the circuit building code", a selfachecking device structure redundancy
