DAC (Digital to Analog Converter) is the enabling inverse technology of ADC that generates analog output proportionate to given digital input. In most of the control and digital processing system requires the DAC for meddlesome with real world. But most of the digital controlling microprocessor and microcontroller don’t have an on chip DAC integrated peripheral architecture. For such implementing system, an external DAC chip is normally used but it decreases the efficiency of system such as power, cost, area. This paper reports on FPGA based Soft IP design for reconfigurable High Resolution DAC using PWM technique. FPGA (Field Programmable Gate Array) have advantage over to the traditional technology of reconfigurability, shorter time to market and non recurring cost and system on chip ability which reduces the board size with increasing efficiency. This designed soft IP core which can be used in parallel with another included FPGA based architectures.
