Debug Signal that indicates when Soft Device is running?

Is it possible to have a debug signal that indicates when the soft device is running?

@Ahedin: You can use radio notification event to know when the radio is active or not. Read more about it in the Softdevice's product spec.

Most of the times (longest blocking period) that the softdevice occupy CPU are when we have BLE events. So radio notification could basically tell the period that the CPU is occupied.

Another option you can do is to try flipping a GPIO pin in your main application or inside a timer "TICK" handler with Application High priority. This way you can have a look at the logic trace of the pin and see the period when the softdevice occupy the CPU.
