Advantages of ChipScope Pro
ChipScope Pro Cores
Tutorial: Using the ILA (Integrated Logic Analyzer) Core to Debug a Design
Step 1: Create and Implement the Project
Step 2: Add ILA core to the design
Step 3: Debug the Design Using ChipScope Pro Analyzer

3. What is ChipScope Pro?
Software tool that if used early in the creation of a Xilinx FPGA project, greatly increases design and debug speed.
With the ChipScope Pro tools, you can insert a logic analyzer, system analyzer, and virtual I/O low-profile software cores directly into design
Allows you to view any internal signal or node
The signals are captured and then brought out through the programming interface, leaving more pins for FPGA design

4. Why use ChipScope Pro?
Complex FPGA designs can be very time consuming to debug
ChipScope Pro tool can shorten the overall design time
ChipScope Pro is integrated with Xilinx ISE software
In-circuit debugging and verification of many nodes in design
Find out what is happening on the chip at the die level

5. ChipScope Pro Cores Integrated Controller (ICON)
Used for communication between the embedded Integrated Logic analyzer (ILA), Integrated bus analyzer (IBA), and Virtual Input/Output (VIO) low-profile cores
Integrated Logic Analyzer
Used to monitor the internal signals of the FPGA design
Both ILA and IBA require on-chip Block RAM
Virtual Input/Output core
Customizable core that can both monitor and drive internal FPGA signals in real time.
Does not require on-chip Block RAM
Agilent Trace Core 2 (ATC2)
Customizable logic analyzer core, similar to the ILA core but does not use on-chip Block RAM

6. Using ChipScope Pro
Once FPGA design is ready to test, place cores into the design:
Attach internal nodes for viewing to the ChipScope Pro core
Generating the cores by using the Core Generator, Core Inserter tool, or PlanAhead software
Place and route the design in the Xilinx ISE software
Download the bitstream to the device under test and analyze with the ChipScope Pro software

7. Tutorial: Using ChipScope Pro ILA Core to Debug a Design
Design Description:
Push Button that controls a 2 bit state machine
Sinewave selection
Low, mid, and high frequency sine wave generators
LEDs to display the current state
Debouncing circuit
Clean transition from high to low when button is pushed
Dip Switches
Enable or disable debouncing circuit

8. Step 1: Create and Implement the Project
Create a new VHDL project in the ISE Project Navigator
Add the provided project files
Add new ChipScope Definition and Connection File to top level
Regenerate all cores
Change hierarchy to soft
Synthesize design
Copy project and rename

9. Step 2: Add ILA Core to design
Double click .cdc file: opens the ChipScope Pro Inserter tool
Click ICON then Next

10. Step 2 continued Set input trigger ports to 6
Set trigger widths and Match Types to settings in the tutorial file
Move to next tab Capture Parameters to confirm

11. Step 2 continued Connect the ports to debug nets in next tab
Search for clk_bufg in pattern field, click make connections
Repeat for the rest of trigger ports

12. Step 2 continued
Verify connections, save and close core inserter tool

13. Step 2 continued
Right-click Generate Programming File process and change the –g StartUpClk to the JTAG Clock under Startup Option then generate and download programming file to the board

14. Step 3: Debug Design using ChipScope Pro Analyzer
NOTE: Unable to complete these steps due to unsupported Xilinx platform
The tutorial is posted on the Atlas Demo Board SharePoint page
Summary of this step:
ChipScope Pro Analyzer tool to view each sinewave (low, mid, and high frequency) plots, they look correct
Error is in the selection circuit logic, when a button is pressed there is a glitch in the waveform (not a clean transition from different frequencies)
Using the Analyzer, push the button and view the logic waveform to find out that the debouncing circuit was not enabled
