* src: Move toggle coverage emit (recursive array traversal) to "cov-data" from lower. * src: Linearize control flow in cover_add_toggle_items_for. * src, test: Convert toggle coverage to separate cover_item for 0->1 and 1->0. * src: Set "num" by default to 1 -> Becomes valid for statements. Simplify cover chain append logic for COV_ITEM_STMT. * src: Move "num" setting for COV_ITEM_TOGGLE to better place. * WIP: Branch coverage - Conversion to counters. * src: Convert branch items fully to single item per covered item in reports too. * src: Move bin name append for toggle items to cover_add_item. * src: Move FSM state coverage logic to "cover" and make it counter, not flag. * src: Fix typo in Button that gives you coverage exclude command. * src: Move "num" setting for COV_ITEM_TOGGLE to better place. * WIP: Branch coverage - Conversion to counters. * src: Convert branch items fully to single item per covered item in reports too. * src: Move bin name append for toggle items to cover_add_item. * src: Port fixes from #909 and #906 to coverage refactoring. * src, test: Rework expression coverage conversion to counters. * src: Unify reporting of COV_ITEM_FUNCTIONAL to use new conversion to cover_chain_t. * src: Remove Exclude mask from cov_item_t, now handled by single flag. * src: Fix build on MACOS. * src, test: Fix leak in the branch coverage. * src: Rename "num" to "consecutive" to better correspond to its meaning. * src, test: Get rid of the BIN in the exclude file completely. * src, test: Clarify that simultaneous covered + excluded will result in covered. * src: Unify "cover_add_*" API towards lower. * src, test: Merge VCODE_OP_COVER_STMT, VCODE_OP_COVER_BRANCH and VCODE_OP_COVER_EXPRESSION. * src, test: Rename "STATE" to "BIN_STATE" to have the same naming as rest of bins. * NEWS, www: Update documentation and changes. * Apply comments from review. * Revert "src, test: Merge VCODE_OP_COVER_STMT, VCODE_OP_COVER_BRANCH and VCODE_OP_COVER_EXPRESSION." This reverts commit 9daa3dc. * src: Remove unused variable.

After elaborating UVVM-based testbenches with coverage enabled works (Thank you for fixing this issue), nvc asks me to file a bug report while creating the coverage report .
For example, generating the coverage report for the testbench uart_vvc_demo_tb, included with the UVVM distribution in the directory bitvis_uart, triggers the message.
I installed uvvm running nvc --install uvvm.
nvc -c --report=report work/_WORK.UART_VVC_DEMO_TB.elab.covdb
