Systems and techniques for creating a circuit abstraction are described. During operation, an embodiment can identify a set of side loads based on a set of timing paths. According to one definition, a side load of a timing path is a circuit element that is not on the timing path (i.e., the timing path does not pass through the circuit element), but whose input is electrically connected to an output of at least one circuit element that is on the timing path. Next, the embodiment can creating the circuit abstraction by retaining circuit elements and nets on each timing path in the set of timing paths, and retaining an identifier for each side load in the set of side loads. The circuit abstraction can then be used to update timing information during one or more stages of an electronic design automation flow.
