For a chip that is 1x1 cm and assuming there are 8 metal lay

For a chip that is 1x1 cm and assuming there are 8 metal layers, if the on-chip wires have an average pitch of 1 µm, what is the total length of all wires on the chip.

Solution

Area = 1x1 cm² it is Raque equal to the area of 8 layers i.e. 8 x Width x Length

1 cm² = 8 x 1 x 10^-6 m x Length

10^-4 m² = 8 x 10^-6 m x Length

Length = 12.5 metre
