Classification: CPC G  H | IPC G

Claim 11:
12. A security chip comprising:
a plurality of configuration registers, each of the plurality of configuration registers having a corresponding address;
an interface circuit that is configured to receive from a host a predefined sequence of accesses of the plurality of configuration registers for one or more operations to the plurality of configuration registers; and
a pattern detector circuit operationally coupled to both the interface circuit and the configuration registers, wherein the pattern detector circuit is configured to monitor accesses of the plurality of configuration registers and wherein, in response to receiving the predefined sequence of accesses, a processing circuit in the pattern detector circuit is configured to: determine a value indicative of a current version of a netlist for the security chip, and, make the determined value available to be obtained by a read operation by the host at a specific configuration register address.
