🔍The graph-based virtual-environment workflow helps optimize circuit designs such as amplifiers by dividing the process into three stages: graph of circuits, graph surrogate model, and constraint optimization.
🔌To begin the process, a graph of circuits is generated, with each node representing a circuit instance and the edges representing connections between them.
🧪The graph surrogate model is trained using a graph neural network (GNN) on labeled samples, predicting labels for unlabeled samples based on the relationships in the graph.
📈Constraint optimization techniques are then applied to find the most optimal design parameters, taking into account specifications and objective functions.
⏰The dynamic learning framework allows for an iterative process where labeled samples are generated, ranked, and used to further train the GNN, ultimately leading to more optimal design parameters.
