Abstract: Electronic design automation (EDA) of the present disclosure logically places components of the electronic circuitry onto an electronic design real estate to determine an architectural design placement for the electronic circuitry. The EDA evaluates a metaheuristic algorithm starting with an initial placement of components of the electronic circuitry onto the electronic design real estate to provide multiple possible placements for placing these components of the electronic circuitry onto the electronic design real estate. The EDA utilizes the multiple possible placements of the metaheuristic algorithm to train one or more probabilistic functions of a model-based reinforcement learning (RL) algorithm. The EDA evaluates the model-based RL algorithm utilizing the one or more probabilistic functions to determine the architectural design placement.

Abstract: A system performs the operations of a neural network agent and a circuit simulator for analog circuit sizing. The system receives an input indicating a specification of an analog circuit and design parameters. The system iteratively searches a design space until a circuit size is found to satisfy the specification and the design parameters. In each iteration, the neural network agent calculates measurement estimates for random sample generated in a trust region, which is a portion of the design space. Based on the measurement estimate, the system identifies a candidate size that optimizes a value metric. The circuit simulator receives the candidate size and generates a simulation measurement. The system calculates updates to weights of the neural network agent and the trust region for a next iteration based on, at least in part, the simulation measurement.

Abstract: A transmission circuit including an equalizer circuit, a slicer circuit, a signal detection circuit, and a control circuit is provided. The equalizer circuit performs an equalizing operation on an input signal according to preset states to output an equalizing signal corresponding to each preset state. The slicer circuit performs a slicing operation on the equalizing signal to output a slicing signal. The signal detection circuit detects and compares the equalizing signal and the slicing signal and accordingly adjusts the equalizer circuit to one of the preset states. The control circuit receives the slicing signal corresponding to each preset state, compares the slicing signal corresponding to each preset state with a plurality of signal patterns to generate a comparison result, and selects one of the preset states according to the comparison result, such that the control circuit let the equalizer circuit perform the equalizing operation according to the selected preset state.
