Block operations during simulation in Scicos and VSS environments can
naturally be described as Nsp functions. But the direct use of Nsp functions
for simulation leads to poor performance since the Nsp language is interpreted,
not compiled. The methodology presented in this paper is used to develop a tool
for generating efficient compilable code, such as C and ADA, for Scicos and VSS
models from these block Nsp functions. Operator overloading and partial
evaluation are the key elements of this novel approach. This methodology may be
used in other simulation environments such as Matlab/Simulink
