(note: This code is from the tutorial. DNL errors of less than -1 correspond to a missing code. ADC and DAC. Posted by 2 years ago. It is widely used for ASIC designing or lower level design (RTL or lower), but this results in faster simulation and effective synthesis. The ADC is a hard IP macro block, so Altera is not going to give you much low level detail of the innards of the block, but just describe the input and output pins of the block, and what you need to provide from your FPGA code. tran 1ns 1100ns Vresetn resetn GND PWL(0 5 10ns 5 11ns 0 20ns 0 21ns 5 ) Vain ain GND. Some characteristics of Verilog are: It is case sensitive, for example an input named adc_in is different from an input named Adc_in. I recently started developing Verilog modules for the Arrow BeMicro CV board with the goal of implementing linear prediction using Levinson-Durbin recursion. An analog-to-digital converter (also known as an ADC or an A/D converter) is an electronic circuit that measures a real-world signal (such as temperature, pressure, acceleration, and speed) and converts it to a digital representation of the signal. Verilog-A: 8bit Piepeline ADC Part-1. In the code below, we will retrieve data caught by the ADC from the angle of our potentiometer. The available software examples show how to use the single ended input, the differential input and the differential high sensitivity input of the ADC. I've created "supermain. The measured voltage is displayed on the six 7-segment display. But first of all, we have to know that in this board, the potentiometer is linked with the GPIOC and the pin 4. The example we present is for an 8-bit ADC, but you can easily modify the digital output wordlength for any desired accuracy of ADC.
