The Rise of Differentiable Testing
![The DEFT framework establishes a differentiable path for reasoning about physical systems, enabling gradient-based optimization of control policies directly within the physics engine by representing continuous dynamics as [latex] \dot{x} = f(x, u) [/latex], where [latex] x [/latex] denotes the system state and [latex] u [/latex] represents the control input, thus bridging the gap between learned control and provable system stability.](https://arxiv.org/html/2512.23746v1/x2.png)
A new framework, DEFT, uses gradient-based optimization to dramatically improve the detection of hard-to-find faults in integrated circuits.
