👾 Design ∪ Hardware

The RiscvSpecKami package provides SiFive's RISC-V processor model. Built using Coq, this processor model can be used for simulation, model checking, and semantics analysis. The RISC-V processor model can be output as Verilog and simulated/synthesized using standard Verilog tools.
