Abstract
A computer identifies a storage element in a simulation model of an integrated circuit design that, during simulation of the integrated circuit design using the simulation model, is subject to having its value forced. In response to identifying the storage element, an indication of the storage element and the associated clock signal are stored in a database. In response to receiving an input indicating the value of the storage element is to be forced during simulation, a determination is made by reference to the database whether or not forcing of the value is mistimed with reference to the associated clock signal. In response to a determination that the forcing of the value as indicated by the input is mistimed with reference to the associated clock signal, an indication that forcing of the value is mistimed is output.
