This problem has affected at least two people for lab 2, so PLEASE read this
carefully.
When you create a new project, you have the option of a schematic or hdl
project. This option is presented as a two radio buttons at the bottom of
the new project window (where you type in the project name).
you must ALWAYS select schematic!! if not, things won't work and you'll get
errors and warnings whenever you try to implement your design. (basically,
your schematic will be ignored, and the tools will expect you to have
written vhld to describe all that kind of stuff, which you haven't...)
--How can I tell if I selected HDL instead of scematic?
1. in the schematic editor, you can only select "create netlist from
current sheet". the normal "create netlist" option is grayed out.
2. In the project manager, you don't have the functional simulator
3. In the project manager, you have a "systhesis" button instead of the
"implementation" button
4. When you go to implement, some kind of options window opens and asks you
stuff like what the top level file is.
--How can I change my HDL project to a schematic project?
unfortunately, there is not way to automatically convert from one project
type to the other.
However, all is not lost. Follow the instructions from the Space Mangement
document for reconstituting a project, only instead of taking the files from
a zip archive etc, you will take them from your existing project. You need
to create the new project first, then copy the *.vhd, *.sch, *.ucf files
into the new project directory. you will then need to rename them, which
probably means that you need to delete some of the files create for the new
project (ie <proj>.ucf and <proj>1.sch). All this is covered in more detail
in the space management document.
