From 3561f12c7a38465447ca6dea89be623d4d9355bc Mon Sep 17 00:00:00 2001 From: Jaehyun Kim Date: Thu, 2 Apr 2026 21:35:44 +0900 Subject: [PATCH 1/3] 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.

Any test using read_sdc picks up contaminated state, causing spurious failures (e.g., clk2 period 15 vs 20). Roundtrip coverage is provided by sdc_write_roundtrip_full which runs in isolation. Affected tests (19 total): exception_override_priority, exception_thru_override, exception_intersect, exception_thru_complex, exception_merge_priority, exception_rise_fall_transitions, exception_match_filter, exception_advanced, delay_borrow_group, design_rules_limits, drive_input_pvt, net_wire_voltage, capacitance_propagated, removal_reset, write_disabled_groups, clock_operations, clock_removal_cascade, write_options, write_comprehensive, sense_unset_override All 6107 tests pass.
