In this study, the Burke-Shaw chaotic system has been modeled in three different platforms. In the first stage, the chaotic system has been modeled numerically with the RK5-Butcher algorithm, and the obtained time series and phase portraits are presented. In the second stage, the chaotic system has been modeled with analog circuit components. The results obtained from the numerical modeling confirm the validity of the modeling with analog components. In the final stage, in order to study the RK5-Butcher algorithm, the Burke-Shaw chaotic system has been modeled in VHDL, a hardware description language. The results of the FPGA-based and the numerical modeling results have been compared each other and a sufficient validation score achieved. According to the test results, the operation frequency of the FPGA-based chaotic oscillator is 373.094MHz and it can generate a million-data set in 0.796 seconds.
