Sine wave signal occurred on xilinx spartan 3e development board fpga Find ROM sinusoidal signal table, digital signal through a the spi interface write development board 12 DA chip ITC2614. DA converter to generate a sine wave. The ROM depth 32768, a sinusoidal cycle can have up to 32,768 points. Can be set by modifying the phase accumulation value and the ROM table to the frequency of the sine wave output. Program I write on the board measured.
