2 Lab 6: HW/SW System Debug Lab Introduction This lab guides you through the process of performing on-chip hardware/software verification using Chipscope-Pro and the software debugger. Objectives After completing this lab, you will be able to: Add ChipScope Analyzer cores into a system Cross debug with Chipscope Analayzer and the SDK debugger Procedure You will extend the system created in the previous lab by adding Chipscope ICON and IBA cores. The IBA core will be added to the PLB bus. You will set trigger conditions in the Chipscope Analyzer software (running on PC) to capture bus transactions when the value of the count variable is written to the LEDs. When the hardware trigger condition is met, you will see that the software debugger stops at the line of code that was last executed. This lab comprises the following steps: 1. Open the lab 6 project 2. Instantiate Chipscope cores 3. Setup SDK and Chipscope 4. Perform hardware/software verification HW/SW System Debug Lab: 6-1

Complete MicroBlaze System For each procedure within a primary step, there are general instructions (indicated by the symbol). These general instructions only provide a broad outline for performing the procedure. Below these general instructions, you will find accompanying step-by-step directions and illustrated figures that provide more detail for performing the procedure. If you feel confident about completing a procedure, you can skip the step-by-step directions and move on to the next general instruction. HW/SW System Debug Lab: 6-2

$Opening the Project Step 1 Create a lab6 folder under c:\xup\embedded\labs.$

4 Opening the Project Step 1 Create a lab6 folder under c:\xup\embedded\labs. If you wish to continue with your completed design from lab5 then copy the contents of the lab5 folder into the lab6 folder or copy the content of labsolution\lab5 folder into the lab6. Launch Xilinx Platform Studio (XPS) and open the project file located in c:\xup\embedded\ labs\lab6. ❶ Create a lab6 folder in the c:\xup\embedded\labs directory.
