Stage 2 now only completes remaining CSA rounds + carry-select final addition. Pipeline depth: S1=13, S2=22, S3=21, S4=31 (was S1=8, S2=28) Critical path unchanged at 31 (Stage 4), but S1/S2 gap reduced from 20 to 9 for better balance. 100/100 tests pass.

designs. - -CycleAware APIs were removed in pyc4.0 and are not part of v4 authoring. - -## 1. What pyc4.0 enforces - -- `@module` defines hierarchy boundaries that lower to `pyc.instance`. -- Simulation follows a two-phase model: - - `tick()` computes next state - - `transfer()` commits state -- Python control-flow is allowed during authoring, but backend IR must be static - hardware (no residual dynamic SCF/index in backend lanes). -- DFX/probe behavior is first-class and controlled by hardened metadata + trace DSL. - -Authoritative references: - -- `docs/rfcs/pyc4.0-decisions.md` -- `docs/updatePLAN.md` -- `docs/FRONTEND_API.md` -- `docs/TESTBENCH.md` -- `designs/examples/README.md` - -## 2. Environment and quick gate loop - -Build `pycc`: - -```bash -bash /Users/zhoubot/pyCircuit/flows/scripts/pyc build -``` - -Run compiler smoke: - -```bash -bash /Users/zhoubot/pyCircuit/flows/scripts/run_examples.sh -``` - -Run simulation smoke: - -```bash -bash /Users/zhoubot/pyCircuit/flows/scripts/run_sims.sh -``` - -Run semantic regression lane: - -```bash -bash /Users/zhoubot/pyCircuit/flows/scripts/run_semantic_regressions_v40.sh -``` - -## 3. Minimal module - -```python -from pycircuit import Circuit, module, u - -@module -def build(m: Circuit, width: int = 8) -> None: - clk = m.clock("clk") - rst = m.reset("rst") - en = m.input("enable", width=1) - - count = m.out("count_q", clk=clk, rst=rst, width=width, init=u(width, 0)) - count.set(count.out() + 1, when=en) - m.output("count", count) -``` - -Key points: - -- `m.out(...)` creates explicit sequential state. -- `.out()` reads current state. -- `.set(next, when=...)` sets next state with hold-by-default behavior. - -## 4. Authoring with Python control flow - -You can use `if` and `for` in `@module` bodies as authoring sugar. - -```python -from pycircuit import Circuit, module, u - -@module -def build(m: Circuit, rounds: int = 4) -> None: - a = m.input("a", width=8) - b = m.input("b", width=8) - op = m.input("op", width=2) - - acc = a - if op == u(2, 0): - acc = a + b - elif op == u(2, 1): - acc = a - b - elif op == u(2, 2): - acc = a ^ b - else: - acc = a & b - - for _ in range(rounds): - acc = acc + 1 - - m.output("result", acc) -``` - -The compiler must lower this to static hardware before backend emission. - -## 5. Structured interfaces - -For larger modules, prefer `spec` + structured IO to keep port conventions -stable and tool-visible. - -```python -from pycircuit import Circuit, module, spec - -Pair = spec.struct("pair").field("x", width=8).field("y", width=8).build() - -@module -def build(m: Circuit) -> None: - ins = m.inputs(Pair, prefix="in_") - m.outputs(Pair, {"x": ins["x"], "y": ins["y"]}, prefix="out_") -``` - -See `docs/SPEC_STRUCTURES.md` and `docs/SPEC_COLLECTIONS.md` for full patterns. - -## 6. Testbench flow - -Write a host-side `@testbench` with `Tb`: - -```python -from pycircuit import Tb, testbench - -@testbench -def tb(t: Tb) -> None: - t.clock("clk") - t.reset("rst", cycles_asserted=2, cycles_deasserted=1) - t.timeout(64) - - t.drive("enable", 1, at=0) - t.expect("count", 1, at=0, phase="pre") - t.expect("count", 1, at=0, phase="post") - t.finish(at=8) -``` - -Observation points: - -- `phase="pre"` = TICK-OBS -- `phase="post"` = XFER-OBS - -## 7.

Required gate mindset (v4.0) - -For semantic or IR-contract changes: - -1. Update verifier/pass gates first. -2. Implement behavior in dialect/passes, not backend-only fixups. -3. Re-run smoke + simulation gates and preserve logs. -4. Keep decision status current in `docs/gates/decision_status_v40.md`. -5. Run semantic closure regressions (`run_semantic_regressions_v40.sh`) before status promotion. - -## 10. Troubleshooting checklist - -- `pycc` not found: run `flows/scripts/pyc build` or set `PYCC`. -- Backend IR legality failures: inspect `pyc-check-no-dynamic` and - `pyc-check-flat-types` diagnostics. -- Hierarchy contract failures: ensure module boundaries are authored with - `@module` and instance creation paths remain explicit. -- Trace decoding failures: verify `.pyctrace` header + `probe_manifest.json` - consistency. - -## 11.
