Lift the legalization owner check so Timing Opt can reuse DreamPlace legalize-only, load ECC from explicit DEF/Verilog, and skip the pre-sizer input DB.
Stage Sizer DEF/Verilog under data/to, rebuild ECC from those files, run DreamPlace legalize-only, and publish only the post-legalize layout. Drop the cached EngineDB after any sizer terminal state.
Honor read_def failure, close abandoned engines, and load explicit sources once. Fill the workspace DreamPlace config path before inner legalization if the map is empty.
Clear previous staging before launching Sizer, and delete published Timing Opt files on every unsuccessful save, including exceptions.
Raise if staging or published artifacts cannot be deleted, and reset Timing Opt subflow stages at the start of every Sizer attempt.
Register Timing Opt/sizer workspace configs so `ecc config` can inspect the db and DreamPlace files the inner legalize path actually reads. Split the oversized sizer runner tests into runner, cleanup, and EngineFlow modules.
Restore create_db_engine(workspace, step). Timing Opt inner legalize now replace()s a local step with staging DEF/Verilog and db=None instead of adding loader kwargs.
Opening an old one-stage Sizer workspace rewrote subflow stages to Unstart but left the outer step Success, so resume skipped Timing Opt and routed the unlegalized DEF. Persistently unstart the owner and its downstream suffix when that rewrite happens.
Insert sizer Timing Opt into the default rtl2gds/harden sequence between legalization and routing so CTS cleanup still happens first and Sizer sees a legal layout.
Download the latest successful linux-x64 Sizer build before pytest and export PATH plus CHIPCOMPILER_ECC_SIZER_ROOT so default-flow Timing Opt can run in CI.
Stop opening step.log.file with write truncation. Sizer now inherits the EngineFlow stdio capture so GUI still shows the sizer error when inner legalize later writes its own DreamPlace log.
Sizer now exposes build_step_metrics so EngineFlow can write qor_metrics/summary after a successful Timing Opt. Reuse the legalization DB summary and skip the Sizer binary check so QoR refresh still works when Sizer is only needed at run time.
