The screen timing generator setup should be performed first since this is usually

generator should still stay disabled until all other settings are complete.
In a second step the resource assignment for a particular display scenario should
be set up. This involves two sub-steps:
–
0
P
I
Each functional unit, whether it is located inside a layer or in the resource pool,
should be assigned to an aperture slot in the overall QVCP aperture.
