Known ISE bugs and work-arunds (v13.2)

(This list will be refreshed periodivally on demand)

• Do not switch keyboard language with shurtcut keys! (ISE crashes) Use the taskbar icon instead!
• In some cases, ISE does not "detect" the ucf file added to the project, and you get a bit-file with random pinout.
  After creating a new ucf, remove it from the project and readd it as an existing source, or
  for smaller designs, you can simply ReRun All, if your design does not work.
• If you can not add the ucf, because top module is missing according to ISE, select any module as the top one, and after that, reselect the real top module!
