The aspect ratios of different core shapes are given in below :

The Role of Aspect Ratio on the Design:

• The aspect ratio effects the routing resources available in the design
• The aspect ratio effects the congestion
• The floorplanning need to be done depend on the aspect ratio
• The placement of the standard cells also effect due to aspect ratio
• The timing and there by the frequency of the chip also effects due to aspect ratio
• The clock tree build on the chip also effect due to aspect ratio
• The placement of the IO pads on the IO area also effects due to aspect ratio
• The packaging also effects due to the aspect ratio
• The placement of the chip on the board also effects
• Ultimately every thing depends on the aspect ration of core/block/design
