Claim Text:
1. A method comprising: (a) receiving a bit value from a TDO (Test Data Out) terminal at an automated test equipment (ATE) system; (b) supplying a replacement bit value to a TDI (Test Data In) terminal and sending a control signal to an input terminal from the ATE system based on determining from a Procedure Description Language (PDL) command of a set of PDL commands whether a bit value of a configured scan path is to be replaced with the replacement bit value, wherein the control signal causes one of the bit value and the replacement bit value to be selected; and (c) transitioning a clock signal on a TCK (Test Clock) terminal such that the selected one of the bit value and the replacement bit value is shifted into the configured scan path on a bit-by-bit basis based on interpreting the set of PDL commands, wherein the configured scan path is shifted thereby outputting a new bit value onto the TDO terminal, and repeating (a) through (c), and wherein the set of PDL commands indicates selection of the replacement bit value for at least one scan path location of the configured scan path and selection of at least one bit value for at least one other scan path location of the configured scan path.
