Hi @alirezatalesh,
Please keep one topic per thread, this will help other users to find the correct posts.
Thank you for pointing out the interest and need for the PSD on ICs. Currently, we currently are short of resources to implement it immediately, but we're looking forward to work on it, and other ICA improvements. If this is feature, you really need, and you know coding in Brainstorm, we love and are open to collaborations to make it happen.
Check this document on collaboration to Brainstorm:
