- The chip consists of a complex logical design. Write the RTL code, synthesis and draw the layout for the entire chip is a tedious job. So, engineers come with a solution is that cut the design into the small-small block and it will help the designer to do his job.
- Therefore, the chip is normally partitioned into sub-chips. These sub-partitions are called blocks. A partition or block or subsystem is a grouped collection of components and cells.
- The actual partitioning process considers many factors such as the size of the blocks, number of blocks, and number of interconnections between the blocks.
Why we need partitioning?
- ?It helps to reduce the chip area
- It will provide a good quality of placement and routing
- Chip performance depends on interconnect and so, we need to reduce interconnection among blocks.?
Main goals of partitioning:?
- Timing constraints have to be satisfied.?
- ?The blocks that are highly connected close to one another
- ?Minimize the delay in critical paths.
