The simulation of modern electronic devices requiring taking into account physical phenomena of different nature such as electrical, mechanical, thermal or fluidic ones. The most of processes are governed by multidimensional partial differentialalgebraic equations (PDAEs). The analytical approach is often insufficient to describe all necessary details of modern devices. On the other hand, using classical finite element analysis (FEA) and boundary element method (BEM) it is difficult to model multidomain devices together with real electrical circuits containing different devices, such as OPAMPs, low voltage or high power devices. In order to simplify the modelling and simulation of recently developed multidomain silicon structures (MEMS, MOEMS and others), the RESCUER programming tool has been proposed and developed. The advantage of proposed approach consists in creation of new generation of compiler, which can translate and optimize specified distributed problems described in the high-level abstraction language into a destination language or equivalent SPICE circuit. This paper presents a application of RESCUER software to the fast multidomain model developing for the modern behavioural simulators such as PSPICE, ICAP, ELDO, AdvanceMS. The micro-channel cooling systems for modern integration systems has been presented as the example.
