ioPlacer

Assign I/O pins to on-track locations at the boundaries of the core while optimizing I/O nets wirelength. I/O pin assignment also creates a metal shape for each I/O pin using min-area rules.

Use the following command to perform I/O pin assignment:

place_ios [-hor_layer h_layer]  
          [-ver_layer v_layer] 
	  [-random_seed seed] 
          [-random] 

• -hor_layer (mandatory). Set the layer to create the metal shapes of I/O pins assigned to horizontal tracks.
• -ver_layer (mandatory). Set the layer to create the metal shapes of I/O pins assigned to vertical tracks.
• -random_seed. Set the seed for random operations.
• -random. When this flag is enabled, the I/O pin assignment is random.

Getting Started

You can find usage information inside OpenROAD app repository, in the "I/O pin assignment" section of the README file.
