Principles for laying out GPU's integrated circuits? (5)
I believe the answer is:
logic
'principles for' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for logic that I've seen before include "Strict reasoning" , "4-ing" , "The science of reasoning correctly" , "Science of correct reasoning" , "Reasoned argument" .)
