“…Designing a synchronous Finite state machine (FSM) is a common task for a digital logic circuit. Sequential circuit optimization has been the subject of intensive investigation for several decades [1] [12]. FPGA synthesis tool provides a variety of design constraints which essentially helps the designer to meet the design goal such as area and speed optimization to obtain the best implementation logic.…”

Synthesis optimization plays a vital role in modern FPGAs in order to achieve high performance, in terms of resource utilization and reducing time consuming test process. Cell-based design techniques, such as standard-cells and FPGAs, together with versatile hardware synthesis are rudiments for a high productivity in ASIC design. As the capacity of FPGAs increases, synthesis tools and efficient synthesis methods for targeted device become more significant to efficiently exploit the resources and logic capacity. The synthesis tool provides the selection of different constraint to optimize the circuit. This paper presents the design and synthesis optimization constraints in FPGA for Finite state machine. The primary goal of this sequential logic design is to optimize the speed and area by choosing the proper options available in the synthesis tool. More over the work focuses the design of FSM with more processes operates at a faster rate and the number of slices utilized in an FPGA is also reduced when compare to single process. The module functionality are described using Verilog HDL and performance issues like slice utilized, simulation time, percentage of logic utilization, level of logic are analyzed at 90 nm process technology using SPARTAN6 XC6SLX150 XILINX ISE12.1 tool.
