I am new to the field of OPC and had some question regarding test patterns. I understood that test pattern is mapping the design gds to the fabricated structures. It is used to make the rule based table that will help the initial design to be adjusted and thus be printed according to the target.
My question is what is driving the choice of the test patterns for a specific design? How do we know that for this design, i will use these test patterns? Is there somehow a relation that is used by test patterns owners?
Thank you in advance,
