Implement Python output flushing at SV control boundaries#45
Merged
Conversation
- Add output_flush.py utility to flush stdout/stderr - Flush before Python->SV calls (invoke_hdl_f, invoke_hdl_t) - Flush after posting response (response_py_t) to avoid deadlocks - Add comprehensive test with Python->SV function calls - Works with both ModelSim (multi-threaded) and Verilator (single-threaded) - No changes to generated code (DPI wrappers) Fixes issue where Python output buffering made it difficult to correlate Python execution with SystemVerilog execution.
