an environment to aid the synthesis of threephase analogue waveform using ahdl
Abstract: This paper presents a synthesis tool that was developed for generating analogue signals using only digital resources. With the specification at the equation level, the correspondent specification in hardware description language was obtained for certain analogue signal. The tool developed in C language works with the analogue function, which is implemented transforming it in a file with the extension TDF, that is the input for SHDL (Altera Hardware Description Language). Using the Max+Plus II project environment, the file obtained was synthesized at the level of logical gates, in that way, to be implemented in FPGA. Analogue waveforms of practical use, for instance, sine, sigmoid and gaussian, were modeled with different bits amount, synthesized and implements. Tests show the precision and the efficiency of the developed tool. The waveforms were obtained in the MatLab program and then visualized in a digital oscilloscope.
