What is the aspect ratio?

When you talk about aspect ratio, you’re referring to the proportional relationship between an object’s width and height. It’s expressed as a ratio, usually written as “width: height” or “w
.” This ratio gives you a sense of how the width compares to the height, no matter the actual size of the object or image.

The Role of Aspect Ratio on the Design

• Congestion is influenced by the aspect ratio.
• Floorplanning is dependent on the aspect ratio.
• Packaging is also influenced by the aspect ratio.
• The aspect ratio affects the availability of routing resources in the design.
• The aspect ratio affects the placement of IO pads in the IO area.
• The aspect ratio affects the timing and, consequently, the frequency of the chip.
• The aspect ratio impacts the placement of standard cells.
• The aspect ratio impacts the placement of the chip on the board.
• The aspect ratio influences the construction of the clock tree on the chip.

What Is the Aspect Ratio of a Chip?

When you talk about the aspect ratio of a chip, you’re referring to the ratio between its width and height. This ratio is important because it directly affects the overall size and shape of the chip you design.
