Patent ID: 8286043

Claim:
A system comprising: a logic circuit including a fault-graded self-testing part; a test routine including a first set of instructions executable by the self-testing part to perform a self-test which, when executed, causes the self-testing part to: test itself for faulty behavior; determine a first test result of the self-test, wherein the first test result is fault-graded; and provide output data to a test routine output, wherein the output data is based upon the first result; a non-fault-graded test module configured to execute a test application, the test application including a second set of instructions which, when executed, causes the logic circuit to perform the test routine and to determine a second test result based on the first test result, wherein the second test result is not fault-graded, and wherein the test module includes: a control output for activating the execution of the test routine; a first test module input for receiving the first test result; and a test module output for outputting the second test result; wherein the test routine output is not connected to the first test module input, and the output data is provided without passing through the test module.
