An electronic device, an electronic system, or a method may be used for testing an electronic device. The electronic device may include a virtual touch circuit. The virtual touch circuit may be configured to transmit testing data. The testing data may represent sensory input data. The electronic device may include a touch host controller. The touch host controller may be configured to process sensory data inputs. The sensory data inputs may include the testing data. The electronic device may include a validation circuit. The validation circuit may be configured to evaluate performance of the touch host controller. The validation circuit may evaluate the performance of the touch host controller by using the testing data that was processed by the touch host controller. The touch host controller, the virtual touch circuit, and the validation circuit may be included in a single die.
