Adding Your Own Design

💡 A guide to add your own architecture.

Adding your own architecture

To add new P4 architecture, we need to add a new generator file p4_generator.py under the directory ./src/architectures/<architecture_name>. File p4_generator.py is the key component in the P4 generation process which is able to drive the model related file dedicated_p4.py and the use case related filecommon_p4.py to collaboratively generate overall the P4 file.

The p4_generator.py file

In p4_generator.py, the key function is main(*), which will be called by Planter.py. The main(*) is able to call functions in dedicated_p4.py and common_p4.py.

Import functions

from dedicated_p4 import *
from common_p4 import *

main(*) function

• The overview of main(*) function

  def def main():
      # 1. Load configuration from file
      config, Planter_config = load_config(config_file)
      # 2. Write an introduction in your P4 file header
      add_model_intro(p4_file, config)
      # 3. Call functions in ```p4_generator.py```, ```dedicated_p4.py``` and ```common_p4.py```
      #    to generate your P4 file
      return
