摘要： Roughly described, an integrated circuit chip comprises a plurality of peripheral circuits, each peripheral circuit connected to a respective debug unit, the respective debug unit configured to generate debug information of that peripheral circuit; and a plurality of separate stores for receiving debug information, storing debug information, and outputting debug information; wherein in response to a single trigger signal, the debug units are configured to stream their generated debug information to the plurality of separate stores; and wherein each of the plurality of separate stores is configured to receive debug information at a higher stream rate than it outputs debug information.

摘要： A method of functionality testing system circuitry on an integrated circuit chip, the system circuitry comprising a plurality of sub-circuits and the integrated circuit chip further comprising debugging circuitry, the debugging circuitry comprising variability circuitry. The method comprises: at the system circuitry, performing a function by the sub-circuits performing concurrent actions; at the variability circuitry, altering relative timing of the concurrent actions so as to increase the likelihood of one or more errors in the system circuitry's performance of the function; and at the debugging circuitry, recording one or more errors in the system circuitry's performance of the function.

摘要： A supervisory unit configured to supervise interconnect messages passing to or from an interconnect is provided. The supervisory unit is configured to, on receiving an interconnect message: store the interconnect message in a data store; compare the interconnect message to predetermined filter criteria; and select, in dependence on that comparison, one or more actions to be taken with respect to the interconnect message. The one or more actions are selected from the group including: permitting the interconnect message to pass unaltered; blocking the interconnect message from passing and permitting the interconnect message to pass in an altered state; and performing the one or more selected actions with respect to the interconnect message.
