The increasing complexity of modern wireless baseband systems demands the use of rapid prototyping methodologies to provide an early estimation of system functionality and performance. In order to achieve an efficient hardware emulation, the complete system including the analog part should be prototyped. In this work we present synthesizable descriptions of a communication channel module and a sigma delta modulator, suitable for fundamental emulation of wireless baseband environments. By avoiding timeintensive hardware/software cosimulation, a great speedup of the system verification can be attained. In order to assist the designer and speed up the design process we also created an environment for automatically customizing the modules according to a specific scenario.
