Methods and apparatus are described for making a placement sensitive engineering change to meet design for test requirements. One of the methods includes placing a set of new flops in an already placed chip design to meet functional requirements of an engineering change. The already placed chip design is pruned to create a set of valid flops and valid scan chains based on a set of pruning rules. A unified flop database is generated containing physical location and connection information for the new flops and the set of valid flops. A change file for the new flops, selected valid flops, and valid scan chains associated with the selected valid flops is generated meeting allocation and placement sensitive signal connection rules. The new flops are connected to the selected valid flops allowing design for test requirements to be met

One of the examples is to define and use the concept of “Logs/Traces Profile” and “System Logs/Traces Profile” (including a role and the log and trace file locations), and incorporate them within the test design document. Each test design document can be associated to each test case to highlight which logs and traces need to be collected during its execution. In this way, the testers will know which logs and traces to provide to the code developers, when addressing an issue. In this way, developer can investigate the bug, understand them, and be able to fix the problem, especially due to timing, synchronization, and concurrency.

Techniques for programmatically coordinating, and synchronizing execution of, automated testing in event-driven systems. One or more user-provided test system event listeners listen for generated events and updates test system status accordingly. A user-provided test suite definition invokes a test framework interface, thereby defining the structure of a test suite. This test suite is executed, referring to the test system status to determine when to move to a next stage (e.g., to a next test case or next test module). Test system status may also be updated directly from a test case or test module (e.g., when the test designer determines that the tested code will not generate events that can be leveraged for test status information).
