Device Connection

Software Development Platform

XILINX provides complete platform support for CPLD/FPGA development, mainly including: 

- HDL development software: Xilinx ISE
- Simulation software: Modelsim-SE
- In addition to the third-party synthesis, simulation, and other tools to provide a software interface
Hardware Development Platform
   The hardware development platform is very simple, only a PC and a programming cable can be the online configuration of CPLD/FPGA or programming of serial configuration devices.

Connect to PC

Use a USB cable to connect the PC.

Connect to the Target Board

There are three interfaces for Platform Cable USB to connect to the target board.

Software Introduction

Introduction to common FPGA development software

software_name Introduction
Xilinx ISE Xilinx ISE is XILINX's comprehensive PLD development software that supports schematic, VHDL, Verilog HDL, and other forms of design input, with its own synthesizer and emulator embedded to complete the complete PLD design flow from design input to hardware configuration.
SignalTap II SignalTap II, known as SignalTap II Logic Analyzer, is a powerful and useful FPGA on-chip debug tool that captures and displays real-time signals and observes the interactions between hardware and software in a system design.
Modelsim-SE Mentor's simulation software for XILINX CPLD/FPGA with features such as RTL-level and gate-level simulation.

Xilinx ISE Installation

Download Demo to FPGA (No program loss during power failure)

XC3S250E is used as an example to configure the following chips. Platform Cable USB is used as an example to configure the downloader. You need to select the corresponding chip model and downloader during configuration.
After compiling, you can configure the information download, as shown below:

  1. Click Xilinx ISE:
    Xilinx ISE01.png
  2. Open the "LED4.xise" project under the verilog\LED\ directory in the 3S250E sample program (users can open any other project, here the LED program of this development board as an example), as shown in the following figure.
