Input vector monitoring concurrent BIST performs two modes of operation, normal mode and test mode During test mode the test generator value is compared with higher order bits and the output is given to comparator circuit. During normal mode the inputs to the CUT are driven from the normal inputs. The modified SRAM is used to reduce the switching activity hence the dynamic power dissipation can be reduced. The output is verified by response verifier (RV) and the fault is identified using testing. The operating speed is faster since the operation is carried out as parallel process and it is suitable for all the type of IC’s.
