摘要
An apparatus and a method for the synchronization of an asynchronous signal in synthesis and simulation of a clocked circuit are disclosed, in which a circuit to be simulated and tested is described with a hardware description language and the asynchronous signals present therein are marked. For producing a network list, the hardware description language is processed with a synthesis tool, in which a specific synchronization module is inserted at every marking. For testing the time behavior of the signals in the clocked circuit on the basis of the network list, a simulator implements a logic/timing simulation, in which a test of the time behavior is selectively deactivated for each inserted synchronization module. The unknown statusses that still occur are output via a display.
