+# Regression test for https://github.com/The-OpenROAD-Project/OpenROAD/issues/10995
+#
+# A standard cell with exactly one non-power pin (here a tie-high cell whose
+# only signal pin is a small multi-shape Metal1/Metal2/Via1 pin) could fail
+# pin access with DRT-0087/DRT-0085. FlexPA::getEdgeCost's viol_access_points
+# check was placed after the isSource()/isSink() early return, but those are
+# the only kind of edge that exist in the DP graph when an instance has just
+# one real pin, so a rejected access point was never actually avoided on
+# retry.
+#
+# The single instance and its placement below (including the absolute
+# coordinates, which affect access-point/track grid alignment) are taken
+# directly from the design that hit this bug, whittled down to the minimum
+# needed to reproduce it.
