In this paper, design of safety critical logic controller by means of programmable logic and microprocessor is described. The solution is based on duplicated Master-Slave architecture and results comparison from both pairs. The architecture was adapted to a FPGA device with embedded microprocessor -- in considered solution the Atmel FPSLIC was chosen. In design process tasks have been divided between hardware and software parts. The hardware part has been described in HDLs. The software for microprocessor has been written in its assembler or low-level C language. The process of verification that is based on simulation comparisons of solutions obtained in two different ways is also presented.
