 The ``example-design.yml`` file contains basic build system information (how many cores/threads to use, etc.), as well as configurations that are specific to the design we are working on such as clock signal name and frequency, power modes, floorplan, and additional constraints that we will add later on.
 
-Finally, the ``example-tech.yml`` file is a template file for a process technology plugin configuration. We will copy this file, and replace its fields with the appropriate process technology details for the tech plugin that we have access to. For example, for the ``asap7`` tech plugin we will replace the <tech_name> field with "asap7", the Node size "N" with "7", and the path to the process technology files installation directory.

For example, for the ``asap7`` tech plugin, we will replace the <tech_name> field with "asap7" and the path to the process technology files installation directory. The technology plugin (which for ASAP7 is within Hammer) will define the technology node and other parameters.
 
 We recommend copying these example configuration files and customizing them with a different name, so you can have different configuration files for different process technologies and designs (e.g. create tech-tsmintel3.yml from example-tech.yml)
