VHDL of me IEEE Std. 1076 has been designed for modeling of digital circuits, but there is a group of analog and mixed-signal circuits for which it can also be applied. For this group A/D oversampling sigma-delta converters belong - important components of many modem DSP circuits. In this paper some experiences considering VHDL modeling of sigma-delta converters are described. Some simulation results are enclosed to show efficiency of the presented approach. Its features are discussed in comparison to the design method of DSP circuits based on Signal Processing WorkSystem (SPW). This paper also contains examples of VHDL descriptions of this kind A/D converters.
