Summary
On the 2026-06 upgrade, NVDLA partition_c-asap7 reaches 6_final but is setup-negative (WNS −183 ps, util 30.6 %). nangate45 partition_c closes (+0.8 ns); sky130hd partition_c does not finish (separate issue).
Detail
Dense placement + the new resizer leave the partition's longest paths slightly negative. Also carries the new OpenSTA write_sdc UTF-8 workaround (redundant async-reset false-paths removed from constraint.sdc).
Scope
Out of scope without SDC/RTL change. See designs/src/NVDLA/DECISIONS.md. Part of PR #195.
