Pourquoi les noix de coco ont 3 marques de trous ?

Les noix de coco ont trois marques de trou car elles sont accrochées au cocotiers par 3 épaisses racines.
Lorsque les noix de coco se détachent, leurs racines se cassent et laissent 3 trous.
C'est un peu le même principe que pour l'humain, relié à son arbre par ses racines qui ont le rôle de trois cordons ombilicals.
On peut donc dire que les trous sont les nombrils des noix de coco.

The present invention relates to the field of electronic design automation, and in particular, to the analysis and optimization of circuit designs. A conventional method of electronic circuit design, design space exploration, and optimization, involves the selection of a number of parameters, such as device size, wire width, and contact size, and their combinations to obtain the best or optimal performance of a circuit. For example, to find the optimal performance for a given design, the designer must select and evaluate the performance of all the different possible circuit implementations. This task becomes increasingly difficult as the number of possible parameters increases. As a result, there is a need for a method to perform a design space exploration in a manner that reduces the number of required simulations and evaluations of circuit implementations. There is also a need for a method to perform a design space exploration in a manner that can be used to perform an automatic or semi-automatic circuit design. Further still, there is a need for a method to perform a design space exploration that can be used to automatically or semi-automatically optimize circuit designs. Yet further still, there is a need for a method to perform a design space exploration in a manner that reduces the number of simulations and evaluations of circuit implementations.
