Abstract :
A hardware solver for ΔΨ=f(Ψ), by the finite-difference method in 3D is presented. The general architecture is given: several identical processors run in a parallel mode in a PC-type environment. Each processor is a specific circuit (ASIC). The arithmetic unit has been integrated in a CMOS 2 μm technology. Using this circuit to simulate potential distribution in silicon devices shows a drastic reduction of the computation time, 1.7 μs per discretization node against 900 μs by a software approach
