the DECT DSC (DECT standard cipher, four conditionally clocked LFSRs (linear feedback shift registers)) in silicon.
as we had reverse engineered it in 2008.
from a national semiconductor device, sitel today.

its unpolished predecessor. D-FFs (flip-flops) marked. this predated degate, Nitram's silicon reverse engineering suite, but partly inspired it.
am I totally off there, @nitram2342 ?

@starbug ?

@starbug @nitram2342 No. That Image was done by me using gimp

@nitram2342 @mazzoo really? very accurate placing. I also started with ginp and excel. tracing was a pain in the ass

@starbug @nitram2342 hmm, pretty sure. I showed it to you in Balanstr/muc on my 2nd last ThinkPad. it was struggling due to 4GB RAM. you liked the idea of different colors for different cells.
also pretty sure I still have the xcf around somewhere...
