1. A method, comprising:
receiving a bump shape at a bump pattern generation tool of an electronic design system;
determining a minimum antiradial pitch between two instances of the bump shape in a same row having an angular relationship greater than zero, wherein the minimum antiradial pitch is determined based on a keep out region for each of the two instances, the keep out region being used to avoid overlap between the two instances of the bump shape;
generating a radial bump pattern specification wherein pitch between adjacent bump shape instances will be greater than or equal to the minimum antiradial pitch; and
arranging instances of the bump shape in a radial pattern using the radial bump pattern specification.
