Maturity fpga-routedTargets FPGA + ASICDifficulty MediumPriority 1
Small binary CAM with per-entry valid bits, masked (don't-care) search, match vector, lowest-index hit encoding and multi-hit flag; combinational or registered search 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.
