Device macromodel impact on data link performance assessment

The use of simulation and macromodels to assess the performance of a typical interconnecting system is addressed. A receiver macromodel including threshold decision of received signals is proposed, and an efficiency analysis demonstrates that the use of well-designed macromodels for all parts of the transmission chain dramatically speeds up the simulation. A careful discussion of simulated eye diagrams shows that macromodels guarantee timing accuracy even in very long bit sequences.
