Analog Essentials Getting Started Guide

Zedboard Version

Typical System Architecture

Below is a generalized block diagram for the architecture implemented in the FPGA project. One of the key elements is

the logic block that drives each Pmod port. Each Pmod port driver contains a dedicated I

C port, SPI port, UART, and

octal GPIO port. Any of these can be quickly connected to the Pmod port via software control. (The multiplexer setting is

controlled by another internal GPIO port.) This eliminates the need to reprogram the FPGA during testing and evaluation

of various peripheral modules.

Board specific notes

The Avnet Zedboard contains (5) Pmod connectors. However, only connectors JA, JB, JC and JD are driven by the

logic/hardware resources in the above diagram. Pmod connector JE is not connected to the logic associated with this

project.
