Summary
The 2026-06 upgrade is a big step forward for floonoc-sky130hd — the old-tools 1_synth stall is gone and the flow now runs all the way to 6_final.odb. But the final report fails PSM-0069: Check connectivity failed on VSS — many TAP/FILLER/stdcell VGND pins are left unconnected by the default sky130hd PDN under the new tools (PSM-0039 warnings precede it).
Scope
Produces a routed DB but not a clean signoff. Needs a PDN fix (followpin/strap coverage of VSS, likely a pdn.tcl) — out of scope for the flow-knob upgrade. asap7 (+1114 ps) and nangate45 (+1838 ps) floonoc pass clean. See designs/src/floonoc/DECISIONS.md (sky130hd). Part of PR #195.
