Abstract:
A scan chain may be formed throughout an integrated circuit in which the scan chain is coupled to a set of pins via bi-directional input/output (I/O) buffers. A state machine may be provided to control the scan chain. Decoding logic may monitor states and transitions between states and generate pseudo static control signals in response to certain states and transition sequences in order to free up test pins for use as additional scan data I/O pins using a single JTAG IR. A test pattern may be received from an external tester using the set of I/O pins and buffers operating in parallel. The test pattern may then be provided to combinatorial logic circuitry coupled to the scan chain. A response pattern may be captured in the scan chain. The response pattern may then be provided to the external tester using the same set of I/O pins and buffers operating in parallel.

Claim (Index 1):
An integrated circuit (IC) comprising:\n application logic that includes combinatorial logic interconnected with scan cells, wherein the scan cells are coupled to form one or more scan chains; a test access port (TAP) coupled to the scan chains, in which the test access port includes: test control logic coupled to the scan chains; a state machine having a plurality of TAP states responsive to one or more test control signals provided by an external tester, the state machine having a plurality of output state signals generated by the plurality of TAP states; and decoding circuitry coupled to receive a portion of the state signals and to output one or more test control signals that are controllably coupled to the test control logic, in which the decoding circuitry is operable to assert and de-assert the plurality of control signals in response to defined sequences of the TAP states.
