Abstract: An integrated circuit comprising: a plurality of on-chip-instrument-modules; a test-controller-module configured to communicate data with the plurality of on-chip-instrument-modules; a functional-module configured to communicate data with the plurality of on-chip-instrument-modules; and an on-chip-instrument-controller. The on-chip-instrument controller is configured to: for each of the plurality of on-chip-instrument-modules, store an access-indicator; and based on a value of the access-indicator for each on-chip-instrument-module, enable the on-chip-instrument-module to communicate with either: the test-controller-module; or the functional-module.
