Simulations

Step 1: Initialize a directory

Place yourself in an empty directory, for example:

mkdir ~/odatix_example
cd ~/odatix_example

Run the init command of Odatix to create configuration files.

odatix init --examples

Step 2: Choose the designs you want to simulate

Uncomment the simulations you want to simulate in odatix_userconfig/simulations_settings.yml. Those simulations are defined in odatix_userconfig/simulations. Architectures are defined in odatix_userconfig/architectures.

Change the value of nb_jobs in odatix_userconfig/simulations_settings.yml depending on the number of logical cores available on your CPU.

Tip

75% of your number of logical cores is usually a good balance for nb_jobs.

Example:

odatix_userconfig/simulations_settings.yml
 1overwrite:        No  # overwrite existing results?
 2ask_continue:     Yes # prompt 'continue? (y/n)' after settings checks?
 3show_log_if_one:  Yes # show synthesis log if there is only one architecture selected?
 4nb_jobs:          12  # maximum number of parallel synthesis

Step 3: Run the selected designs
