Which "efficient algorithm" uses ADE-XL for global optimization?

desyddd

Hello,

I am working on optimizing a design but the local optimization algorithms are not suffcient since possible solutions are not in the neighborhood of each other.

That is why, I am using global optimization to get more diverse results in terms of the feature space. For better understanding this procedure it would be helpful to get some information about the used algorithm / optimization method. In the documentation, I did not find a more specific description as: (I cite the documentation) "It efficiently searches over all of the variables defined to find a good solution for your design".

Could you please provide a short description or at least the name of the implemented optimzation procedure?

I am looking forward to your answer.

Thank you very much for your time in advance.

Best regards

    First of all, asking this question in the suggestions, questions and feedback forum is not a very good place to get an answer to a technical question. So I moved this into the Custom IC Design forum which is more sensible.

    Global Optimization is Cadence developed internal optimization algorithm which works well in nonlinear design space without needing a good starting design point. We don't reveal details of the algorithm because it is proprietary intellectual property.

    I don't really know why you would need to know the algorithm used to actually use the optimiser.

    Kind Regards,

    Andrew.

    Hi Andrew,

    thanks fot your quick reply. The reason for the question is just curiosity and to better understand the solutions generated using it.

    Kind regards,
