The described embodiments include an interposer with signal routes located therein. The interposer includes a set of sites arranged in a pattern, each site including a set of connection points. Each connection point in each site is coupled to a corresponding one of the signal routes. Integrated circuit chiplets may be mounted on the sites and signal connectors for mounted integrated circuit chiplets may coupled to some or all of the connection points for corresponding sites, thereby coupling the chiplets to corresponding signal routes. The chiplets may then send and receive signals via the connection points and signal routes. In some embodiments, the set of connection points in each of the sites is the same, i.e., has a same physical layout. In other embodiments, the set of connection points for each site is arranged in one of two or more physical layouts.
