Document Table of Contents Common Problems When Reserving a Signal Probe Pin

If you cannot reserve a Signal Probe pin in the Intel® Quartus® Prime software, it is likely that one of the following is true:
  • You have selected multiple pins.
  • A compilation is running in the background. Wait until the compilation is complete before reserving the pin.
  • You have the Intel® Quartus® Prime Lite Edition software, in which the Signal Probe feature is not enabled by default.
  • You have not set the pin reserve type to As Signal Probe Output. To reserve a pin, on the Assignments menu, in the Assign Pins dialog box, select As Signal Probe Output.
  • The pin is reserved from a previous compilation. During a compilation, the Intel® Quartus® Prime software reserves each pin on the targeted device. If you end the Intel® Quartus® Prime process during a compilation, for example, with the Windows Task Manager End Process command or the UNIX kill command, perform a full recompilation before reserving pins as Signal Probe outputs.
  • The pin does not support the Signal Probe feature. Select another pin.
  • The current device family does not support the Signal Probe feature.
