Hi friends
Ans1) Actually we can't check practically that the clock is reaching to all path at the same time. But we can take care of this during clock routing by calculating path depalys and arrenging blocks accordingly. Clocking strategies like H-tree can be used. Thus clock routing is always treated separate
issues in camparison to normal routing.
3) yes
6) Power analysis is done to get the total power, leackage power, static power dissipation and to check wether they are in within limitation or not.
