Methods and apparatus for designing electronic circuits, including analog and mixed signal (AMS) circuits, based on an evolutionary optimization approach. In one exemplary embodiment, the optimization approach is implemented using a computer program running on one or more computers. The optimization program receives inputs from the designer regarding (i) optimization objectives for the design process, and (ii) the constraint mechanisms to be applied. Both constrained and unconstrained optimization formulations can be addressed by the program. Various objective function evaluation mechanisms are implemented. The program also advantageously allows for continuously encoded variables, which are particularly useful for solving AMS design problems.

A method and system for design optimization that incorporates the advantages of both traditional response surface methodology (RSM) and neural networks is disclosed. The present invention employs a unique strategy called parameter-based partitioning of the given design space. In the design procedure, a sequence of composite response surfaces based on both neural networks and polynomial fits is used to traverse the design space to identify an optimal solution. The composite response surface has both the power of neural networks and the economy of low-order polynomials (in terms of the number of simulations needed and the network training requirements). The present invention handles design problems with many more parameters than would be possible using neural networks alone and permits a designer to rapidly perform a variety of trade-off studies before arriving at the final design.

In various embodiments, a generative design application iteratively generates designs via a generative design process. In operation, the generative design application performs one or more layout operations on virtual objects based on a first set of design constraints to generate a first design. The generative design application then modifies the first set of design constraints based on feedback associated with a mid-air representation of the first design displayed in a virtual reality environment to generate a second set of design constraints. Subsequently, the generative design application performs one or more layout operations on the virtual objects based on the second set of design constraints to generate a second design that achieves design goal(s). Advantageously, enabling a designer to incrementally indicate design goal(s) as constraints via a virtual reality environment instead of as a predetermined objective function reduces both the time and effort required to generate designs.
