CIRCUIT MODIFICATION

Techniques for modifying a circuit are described herein. In some examples, a method includes generating a set of testing data and detecting a predetermined modification to a translation path corresponding to a memory address mapping, the predetermined modification to change a physical memory address of the testing data associated with a virtual memory address to a second physical memory address of the testing data. The method can also include generating a test template comprising a first instruction to implement the predetermined modification and a second instruction comprising the second physical memory address in the translation path and transmitting the test template to the circuit for each of a plurality of software instruction threads. Furthermore, the method can include detecting a defect in the execution of the test template by the circuit and modifying the circuit to prevent the defect during execution of the test template.
