Optimizing the single FPGA board resource as a simulator in a multi user environment regardless of the physical distance improved by TCP/IP. It is important step for IP and system development to use FPGA and IP core to design and improve flow of multi user data in a high speed communication internet environment and optimal utilization of available bandwidth. A user can connect either by Wi-Fi, Wi-Max , USB, PCI or over a network connection may be to another workstation. There is no need for end users to program this functionality at their own ends. In this paper, we have shown that with Xilinx's system generator for, it is possible for multi users to hardware co-simulate IP Cores over any distance via TCP/IP and at any altitude of angle using NLOS Wi-Max, sharing only one FPGA resource. The strategy is based on the time sharing modular approach (TDM), mutually exclusive phenomena. To enhance security of FPGA and IP core co-simulated users we use strong encryption standards. In this paper we have used three encryption standards AES and Camellia and DES. Matlab 7.0 is used ensuring sharing of FPGA board in a multi user, insecure environment to make possible efficient use of FPGA board resource.
