How do I modify the given TCL script to make pin assignments?
See also Section 12: Advanced Topics. To ensure that all pin assignments are made correctly when running the TCL script, you will have to verify that your project, its top level design, and all its pins have names which correspond with those given in the TCL script. You may therefore modify either the TCL script or your design to achieve this. To make your life easier, it is a good idea to first look at the TCL script given to you for the lab before beginning. This way you can simply use the same names for everything and not have to worry about changing the script or your design later on.
