Now a days chaotic systems have an important role in secure communication and cryptography. As FPGA implementation have certain advantages over analog one, different chaotic system like chaotic oscillator, True random number generators and chaotic systems used in image processing, optical circuits for secure communications were successfully realized in FPGA. This paper presents FPGA implementation of Autonomous Pandey-Baghel-Singh chaotic signal generators using Heun algorithm. Numerical solution of Differential equation system is obtained and coded in Verilog and tested with Xilinx vivado 17.3 design suite in Artix-7 Nexus 4 DDR and Basys 3. Performance of the FPGA based chaotic generators is analyzed using 106 data sets with the maximum operating frequency achieved up to 359.71 MHz.
