Behavioural simulation is the common alternative to the costly electrical simulation of ΣΔ modulators (Sgr;Dgr;Ms). This paper explores the behavioural modelling and simulation of ΣΔMs by using hardware description languages (HDLs) and commercial behavioural simulators, as an alternative to the common special-purpose behavioural simulators. A library of building blocks, where a HDL has been used to model a complete set of circuit non-idealities influencing the performance of ΣΔMs, is introduced. Three alternatives for introducing ΣΔM topologies have been implemented. Experimental results of the simulation of a fourth-order 2-1-1 cascade multi-bit ΣΔM are given.
