variables crossing clksleep in timed scopes In timed scopes, variables defined before a clksleep and used after it are now kept as reg (not aliased to wire). This prevents incorrect behavior where a wire reflects the current input rather than the latched value at the point of assignment. Only clksleep is treated as a clock boundary; wait_until and its derivatives are excluded because they can pass in 0 clocks. --- polyphony/compiler/ir/analysis/regreducer.py | 72 ++++++++++++++++++-- tests/timed/timed_reg_test.py | 40 +++++++++++ 2 files changed, 108 insertions(+), 4 deletions(-) create mode 100644 tests/timed/timed_reg_test.py diff --git a/polyphony/compiler/ir/analysis/regreducer.py b/polyphony/compiler/ir/analysis/regreducer.py index 8924a24..2d22843 100644 --- a/polyphony/compiler/ir/analysis/regreducer.py +++ b/polyphony/compiler/ir/analysis/regreducer.py @@ -1,3 +1,4 @@ +from collections import deque from ..ir import * from ..irhelper import qualified_symbols from ..irvisitor import IRVisitor @@ -6,12 +7,69 @@ logger = getLogger(__name__) +def _is_clksleep(stm): + """Check if stm is a clksleep call (excludes wait_until and wait_*).""" + return (stm.is_a(EXPR) and stm.exp.is_a(SYSCALL) and + stm.exp.name == 'polyphony.timing.clksleep') + + class AliasVarDetector(IRVisitor): def process(self, scope): self.usedef = scope.usedef self.removes = [] super().process(scope) + def _has_clksleep_between(self, def_stm, use_stm): + """Check if there is a clksleep between def_stm and use_stm.""" + def_blk = def_stm.block + use_blk = use_stm.block + if def_blk is use_blk: + stms = def_blk.stms + in_range = False + for stm in stms: + if stm is def_stm: + in_range = True + continue + if stm is use_stm: + return False + if in_range and _is_clksleep(stm): + return True + return False + # Different blocks: check if any CFG path from def_blk to use_blk contains a clksleep + # First, check if def_blk has a clksleep after def_stm + stms = def_blk.stms + found_def = False + for stm in stms: + if stm is def_stm: + found_def = True + continue + if found_def and _is_clksleep(stm): + return True + # BFS from def_blk to use_blk + visited = set() + queue = deque(def_blk.succs) + while queue: + blk = queue.popleft() + if blk in visited: + continue + visited.add(blk) + if blk is use_blk: + # Check if use_blk has a clksleep before use_stm + for stm in blk.stms: + if stm is use_stm: + break + if _is_clksleep(stm): + return True + return False + # Intermediate block contains a clksleep + for stm in blk.stms: + if _is_clksleep(stm): + return True + for succ in blk.succs: + if succ not in visited: + queue.append(succ) + return False + def visit_CMOVE(self, ir): assert ir.dst.is_a(IRVariable) sym = qualified_symbols(ir.dst, self.scope)[-1] @@ -95,11 +153,17 @@ def visit_MOVE(self, ir): return elif ir.src.is_a(ARRAY): return - stms = self.usedef.get_stms_defining(sym) - if len(stms) > 1: + def_stms = self.usedef.get_stms_defining(sym) + if len(def_stms) > 1: return - stms = self.usedef.get_stms_using(sym) - for stm in stms: + use_stms = self.usedef.get_stms_using(sym) + if sched == 'timed' and def_stms: + def_stm = next(iter(def_stms)) + for use_stm in use_stms: + if self._has_clksleep_between(def_stm, use_stm): + logger.debug(f'{sym} crosses clksleep, keeping as reg') + return + for stm in use_stms: if sched != 'pipeline' and stm.block.synth_params['scheduling'] == 'pipeline': return if sched != 'parallel' and stm.block.synth_params['scheduling'] == 'parallel': diff --git a/tests/timed/timed_reg_test.py b/tests/timed/timed_reg_test.py new file mode 100644 index 0000000..23b678b --- /dev/null +++ b/tests/timed/timed_reg_test.py @@ -0,0 +1,40 @@ +from polyphony import module +from polyphony import testbench +from polyphony.io import Port +from polyphony.timing import timed, clkfence + + +@timed +@module +class timed_reg_test: + def __init__(self): + self.i = Port(int, 'in') + self.o = Port(int, 'out', 0) + self.append_worker(self.w) + + def w(self): + clkfence() + x = self.i.rd() + clkfence() + y = x + 10 + self.o.wr(y) + clkfence() + self.o.wr(x + 20) + clkfence() + + +@timed +@testbench +def test(): + m = timed_reg_test() + m.i.wr(5) + clkfence() + m.i.wr(99) + clkfence() + clkfence() + x = m.o.rd() + assert x == 15 + clkfence() + x = m.o.rd() + assert x == 25 + clkfence() From 8930ae3f0be184a83818a2ef474cae5c66e4fe50 Mon Sep 17 00:00:00 2001 From: Hiroaki Kataoka Date: Fri, 13 Mar 2026 14:43:12 +0900 Subject: [PATCH 22/30] feat: Python simulation debug feature (watch/VCD/text log) Add SimulationObserver for signal change logging and VCD output in Python simulation.
