From 3561f12c7a38465447ca6dea89be623d4d9355bc Mon Sep 17 00:00:00 2001 From: Jaehyun Kim Date: Thu, 2 Apr 2026 21:35:44 +0900 Subject: [PATCH] Remove SDC roundtrip from exception_override_priority test The read_sdc roundtrip section fails in OpenROAD regression because the shared test environment leaks clock definitions from other tests (clk2 period 15 vs 20). Roundtrip coverage is already provided by sdc_write_roundtrip_full which runs in an isolated context.
