Detailed Description

The top module instantiates

• The ADC channel register map.

• The ADC common register map.

• The AXI handling interface.

The data from the interface module is processed by the ADC channel module. The Up_adc_common module implements the ADC COMMON register map, allowing for basic monitoring and control of the ADC. The Up_adc_channel module implements the ADC CHANNEL register map, allowing for basic monitoring and control of the ADC’s channel.

Design Guidelines

The control of the chip is done through an SPI interface, which is needed at the system level. The Interface must be connected directly to the top file of the design, as IO primitives are part of the IP.

The example design uses a DMA to move the data from the output of the IP to memory. If the data needs to be processed in HDL before moving to the memory, it can be done at the output of the IP (at the system level) or inside the ADC interface module (at the IP level).

The example design uses a processor to program all the registers.

If no processor is available in your system, you can create your IP starting from the interface module.

Software Guidelines (if necessary)
