Synthesis of Built-in Self-Test Control Circuits Based on the Method of Boolean Complement to Constant-Weight 1-out-of-n Codes

Resumo

We consider the problem of designing a built-in control circuit with full self-testability of control equipment based on the method of Boolean complement to constant-weight 1-out-of-n codes. A method is proposed for determining complementary functions considering the formation of the necessary set of test combinations for a complete check of each element of modulo-2 addition in the structure of the Boolean complement block. Due to the introduction of uncertainties in the selection of values, it is possible to minimize the complexity of control functions, which makes it possible to simplify the control logic block. An algorithm for the synthesis of a built-in self-test control circuit based on the method of Boolean complement to a preselected constant-weight 1-out-of-n code is given.
