Abstract
The disclosure provides a general solution for determining connections between terminals of various types of circuits using machine learning (ML). A ML method that uses reinforcement learning (RL), such as deep RL, to determine and optimize routing of circuit connections using a game process is provided. In one example a method of determining routing connection includes: (1) receiving a circuit design having known terminal groups, (2) establishing terminal positions for the terminal groups in a routing environment, and (3) determining, by the RL agent, routes of nets between the known terminal groups employing a model that is independent of a number of the nets of the circuit. A method of creating a model for routing nets using RL, a method of employing a game for training a RL agent to determine routing connections, and a RL agent for routing connections of a circuit are also disclosed.
