Data streaming for testing identical circuit blocks

One or more non-transitory computer-readable media storing computer-executable instructions for causing a computer to perform a method, the method comprising:

• creating a system in a circuit design for a circuit, the system comprising:
• a first network comprising first data channels and first interface devices, the first interface devices comprising registers and clock signal generation logic, each of the first interface devices being coupled to ports of one of circuit blocks in the circuit, the first network configurable to transport a plurality of data packets consecutively, each of the plurality of data packets having m bits, each of the m bits being assigned to one of the circuit blocks preconfigured in an active mode, m being equal to or greater than a number of first data channels used for the transporting the plurality of data packets,
• wherein the circuit blocks comprise a set of identical circuit blocks, ports of each of the set of identical circuit blocks comprise inputs and outputs of scan chains, inputs and outputs of one or more test controllers, or a combination thereof, and each of the first interface devices coupled to ports of each of the set of identical circuit blocks further comprises comparison circuitry;
• and
• a second network comprising one or more second data channels and second interface devices, each of the first interface devices being coupled to one of the second interface devices, the second network configurable to transport configuration data to the first interface devices, the configuration data comprising data for determining whether or not a first interface device in the first interface devices is activated and data for determining which bit or bits of each of the plurality of data packets to be captured, replaced, or captured and replaced by each of the first interface devices activated,
• wherein when at least one of the first interface devices coupled to the ports of the set of identical circuit blocks is activated, each of the plurality of data packets comprises one or more bits of a test pattern or a compressed test pattern for testing a circuit block in the set of identical circuit blocks and one or more bits of good-machine test responses to the test pattern or the compressed test pattern.
