Reverse Engineering the ARM ALU

Interesting write-up. Silicon chips are a work of art. Reverse engineering on the silicon level likewise. Acorn doesn’t produce any chips themselves. They sell the IP. Its up to the fabricators to turn the IP in to real chips. Some of the IP are available in VHDL or “blackbox”. I’ve used ARM-cores before in an FPGA. I’m wondering if it would possibly be easier to rip the files generated for the FPGA than reverse engineering the silicon. The output will change with the optimisation settings… So it will not be exactly the same. Other than that writing a behavioural model in VHDL would give the same functionality.
