Sequential divider (restoring / non-restoring)
Maturity fpga-routedTargets FPGA + ASICDifficulty MediumPriority 1
Radix-2 sequential integer divider, one quotient bit per cycle. ALGO selects restoring or non-restoring; SIGNED gives C/RISC-V truncating division with RISC-V divide-by-zero and overflow results.
FPGA-routed. The block meets timing on a routed FPGA netlist at a stated clock and its testbench passes on that netlist. It has not yet run on a board or in silicon.
