Error: top level design entity " " is undefined

I see that your project is set to a top level entity "DramControl", but there's no file with this name. The bdf file apparently intended as top level is "DramCltGen.bdf". It can't work this way.

If you open DramCltGen.bdf, you can set it as top level entity in the project menu.

As the next problem, DramCltGen.bdf has illegal pin names containing a "#".

There are additional logic errors and possible problems in the design, e.g. an internal tris-state buffer that is causing an 'U' unknown logic state, when disabled.

P.S. Regarding:

--- Quote Start ---

I was not able to get any *.qar file.

--- Quote End ---

I believe, that you get an error message, but a valid *.qar file has been generated and is contained in your *.zip file anyway.
