For testing automatically generated C compiler for embedded systems on simulator, it is necessary to have corresponding support in the simulator itself. Testing programs written in C very often use I/O operations. This functionality can not be achieved without support of the C library. Hence, the simulator must provide the interface for calling the functions of the operation system it runs on. In this paper, the authors provide a method that enables running of programs, which use functions from the standard C library. After the implementation of this approach they are able to use the function provided by the C library with limitations given by the hardware.
