Checking whether complex digital systems work properly is a hard, tedious and repetitive task. If this digital system involves the transmission of data through the use of communication devices, the testing becomes a hard problem to solve: signal power is low and it is prone to interference, baseband signals are complex and transmitted data is hard to detect directly in the waveform, transmission errors appear at random and most systems must be able to cope with maliciously sent frames, designed to make the system crash. Nowadays security and reliability is a priority in communication systems, so an automated process with a user-friendly interface, which is simultaneously flexible enough to enable all the feasible proofs, will no doubt the designer to find the possible mistakes made in the implementation. In this paper, we propose an approach to a testbench architecture, which enables the communication system designer work with any emerging network protocol, and that can be easily implemented in a laboratory.
