AON Cell
AON Cell In low power design, when we have always on power domain and switchable domain (ON/OFF Power Domain) and the cells are interacting between these domains then we need AON Cells which remains ON during OFF state of switchable…

Decap Cells
Decap Cells Decap cell is basically a capacitor cell which is used temporarily in the design between power and ground rails to counter the functional failure. We cant have functional failure in our design. So to avoid any kind of…
Blockages in VLSI
What are Placement and Routing Blockages in VLSI? There are basically two types of blockages in VLSI,.i.e., Placement Blockages and Routing Blockages. The Placement Blockages are again classified into three types. They are hard blockages, soft blockages and partial blockages.…
Floorplan Module Constraints in VLSI
What are Floorplan Module Constraints in VLSI? There are basically five different type of module constraint. They are as follows: None A module has the attribute None, if it is not preplaced in the core design area. A module can…
Macro Placement Guidelines
Macro Placement Guidelines After Pin placement, we place macros in the design keeping in mind below rules: One thing I am sure that if you read the below points carefully, you will be able to easily place macros for any…
Macros in VLSI
What are Macros? Macro Cells are the Memory cells. These IPs have been designed by some other Analog design team, which can be used in the floor plan stage of the design. Type of Macros There are following three types…
Floorplan
What is Floorplan? Before hitting this particular topic of Floorplan, let’s take an example of building a house. If we are going to build a house, we first specify the area for different rooms, such as balcony, kitchen, lawn, etc.…
