We need to fill the Wiki with research results and bring the research that has not been done yet.

• [ ] SoC overview (composition and layout of the main modules, chip revisions)
• [x] Links to other researchers
• [ ] Description and schematics of I/O terminals of the chip
• [x] Library of standard cells
• [ ] Macro-cells (memory)
