/rohd-rtl-gotchas
Use when building or testing RTL in ROHD (Dart), rohd_bridge, or rohd_hcl and hitting hierarchy-violation errors, "Bad state: No element" at sim setup, co-simulation failures, SystemVerilog emission name mismatches, or unexpected register read latency

Other skills on claude-for-hardware.
- /bare-metal-bringup
Use when bringing up bare-metal or kernel code on a new architecture, SoC, or board (RISC-V, ARM, x86, ESP32) and it won't boot, hangs after boot, or faults early; covers trap vectors, MMU/PMP, syscall ABI, and boot ordering
Open skill - /codegen-validation
Use when building or debugging a compiler backend, codegen, or assembler and you need to prove the generated machine code is correct by executing it on a real CPU or a fast emulator, not just inspecting the output
Open skill - /differential-verification
Use when verifying a hardware DUT (a CPU core, FPGA, or netlist) against a golden reference model, building coverage-guided fuzzing, or detecting where silicon diverges from a simulator like Spike, an emulator, or SPICE
Open skill - /firmware-boot-chain
Use when building or debugging a firmware and boot chain (RISC-V SBI, UEFI, ACPI, a bootloader handoff like Limine to an OS) or adding measured boot with a TPM, and a stage fails to hand off to the next
Open skill - /fpga-bringup
Use when loading a bitstream onto a physical FPGA and driving or observing it over JTAG or GPIO, especially bit-banged JTAG from a host like a Raspberry Pi, or when configuration silently fails
Open skill - /fpga-synthesis-fit
Use when synthesizing RTL to an FPGA with yosys/nextpnr (ECP5/Lattice and similar), fighting area or routing congestion, measuring Fmax, deciding why a design won't fit or route, or instantiating block RAM; covers the pre-pack vs post-pack metric trap
