From 2d2762437ad7e8f05baa46587d972dc1627c583e Mon Sep 17 00:00:00 2001 From: Jaehyun Kim Date: Fri, 20 Feb 2026 21:07:40 +0900 Subject: [PATCH] test: Remove unnecessary catch blocks from Tcl tests across all modules Remove bare catch blocks that silently swallowed errors instead of properly testing them. Fix underlying issues revealed by catch removal including wrong API calls ([$role name] on strings, invalid properties like cell_leakage_power/is_register, nonexistent Tcl bindings) and incorrect library names. Update golden .ok files to match new output.
