Lab 3 Tips

Lab 3 is a fairly straight forward lab this week. It uses a TA designed macro that in theory should attach to your lock system and allow you to use the XILINX board as an actual interactive lock.

KEY: Understand how the macros given to you interfaces with the boards (i.e. pins, LCD, buttons).

OPADs and IPADs:

- These are input and output signal interfaces which allows your internal logic system to interface with the chip and any outside devices.

- Study the given macros to you and understand how for example the RESET signal is fed into your system and how the STATE signals are fed out of your system and onto the board.

- Each OPAD and IPAD is tied to a certain pin and that pin is denotated, i.e. LOC=P45

Implementation:

- When implementating your design so it can be downloaded to the board, observe the compiling window to montiore number of CLBs, errors, warnings, etc.

- When reimplementing your design due to improvement or a bug, sometimes removing all the original implementation data will remove any errors in recompiling.

- From the Project Manager window, go to: Project --> Clear Implementation Data

- Click here for an example of removing Implementation Data.

The Board:

- Do not force the X-Checker cable onto the interface pins. They plug in a certain way, don't use brute force.

- Make sure you ground yourself anytime you have to touch the board. There should be a ground pad at your station, and if not, touching the screws of the computer will ground you as well.

- Make sure all wire-wraps are in place and that the spare button is wired correctly. The spare button will be your ENTER button in this lab.
