Whenever you use OCEAN, it uses an ADE license. The spectre license is used during simulation - bear in mind that by default spectre runs in "interactive" mode which means that the simulator keeps running, so that doing parametric analysis, or even just calling desVar() to change a parameter and then run() again, it is faster because it doesn't need to re-invoke spectre, re-obtain the license, and re-read the netlist.

You can stop that by doing:

envSetVal("spectre.envOpts" "controlMode" 'string "batch")

but bear in mind this will slow down such sweeps as I describe above.

If you are using OCEAN for post-processing only, it will still use an ADE license (but not a spectre license).
