This course is totally about VLSI design practical approach and it’s related to another thing which is basic for design VLSI.
What will students learn in this course?
The students are going to learn about physical design, the very essential process to make an integrated chip. This process of physical design consists of various steps and all of them are interrelated.
We have designed this video lecture to provide students in-depth exposure to the subject with clarity that none of the material is out of the prescribed syllabus.
Each part has consisted of the brief but necessary information with the entire requisite.
Who are the target students?
All the undergraduate, graduate, and working professionals who are in need to have a quick and appropriate knowledge platform.
They would get necessary and required information with crystal clear diagrams and graphics.
The design and optimization of integrated circuits (ICs) are essential to the
production of new semiconductor chips.
The design-cycle of VLSI-chips consists of different consecutive steps from high-
level synthesis (functional design) to production (packaging).
The physical design is the process of transforming a circuit description into the
physical layout, which describes the position of cells and routes for the
interconnections between them
The physical design produces an Integrated chip for use in application ranging from
military, consumer appliances, entertainment gadgets, mobile, and so on.
The main concern is the physical design of VLSI-chips is to find a layout with
minimal area, further the total wire length has to be minimized
Due to its complexity, the physical design is normally broken in various sub-steps:
1. First, the circuit has to be partitioned to generate some (up to 50) macrocells.
2. In the floorplanning phase, the cells have to be placed on the layout surface.
3. After placement, global routing has to be done. In this step the `loose'
routes for the interconnections between the single modules (macrocells) are
4. In the detailed routing, the exact routes for the interconnection wires in the
channels between the macrocells have to be computed.
5. The last step in the physical design is the compaction of the layout, where it
is compressed in all dimensions so that the total area is reduced.
This classical approach of the physical design is strongly serial with many
interdependencies between the sub-steps.
