fix validation for unsupported operation

 Use `--skip-non-functional-simulation` when latency and power are not required.
-The summary reports non-functional results as measured, failed, or skipped.
+The summary reports non-functional results as measured, failed, unsupported, or
+skipped.
+
+Overall PASS/FAIL is determined by compilation and functional output
+comparison. A non-functional simulation failure remains visible as `ERROR` in
+the latency and power columns but does not change a functional PASS.
+
+`pimsim-nn` does not currently implement the `vsoftmax` instruction. When its
+explicit unsupported-op diagnostic is encountered, Softmax validations retain
+their functional PASS and show `UNSUPPORTED` in both non-functional columns.
+Other `pimsim-nn` failures remain `ERROR`.
