I 've ready gone through Whitepaper-CW305 and searched through the RTFM, but there are things not thoroughly covered like the subsection of Switches, where only the function of J16 & K16 are described. In the end of the session it is stated that “See the example design documentation for more details.”.
p.s. [I 've successfully attacked the AES using CPA and another attack using DFA(clocking the CW305 from the Chipwhispere-Lite)]
Hi Antonis,
The DIP switches are inputs to the FPGA. In our example AES design, J16 and K16 are used for clock routing; the others do nothing: chipwhisperer/cw305_top.v at develop · newaetech/chipwhisperer · GitHub.
Let me know if you have any other questions!

Thank you @jpthibault Jean-Pierre, for your quick response! Yeah, I was already aware of what the J16 & K16 functions, since I’ve used them in both attacks I’ve tried. I was just curious about the K15 & L14. I will take a look in the links shared!
