Clock mesh and Clock tree-type distribution system

Clock mesh technology provides uniform, low-skew clock distribution and offers better tolerance to on-chip variations (OCV) than conventional clock trees.

What is a Clock mesh distribution system?

Clock mesh distribution systems are

• There are additional design stages.
• Power loss is considerable.
• Implementation complexity
• The multi-driven net is connected to the mesh network via mesh drivers.
• The clock skew and clock insertion delay is greatly reduced.
• To create clock meshes, more routing resources are needed.
• The arrival time difference from several mesh drivers is rounded off by the presence of a mesh net.

What is the Clock tree distribution system?

Clock tree distribution systems are

• Low power is dissipated.
• There is no need for a mesh net.
• The best design phases span a number of phases.
• It works best with circuit designs with slow clocks.
• A clock source, clock tree cells, clock gating cells, buffers, and load are all components of the clock tree.
