Pull request overview
This PR backports the underflow fix for OBI typedef signal widths onto the common-cells-v2 branch by introducing a “minimum width” macro and applying it to width-dependent packed-array typedef fields to prevent [0-1:0] underflows in simulators.
Changes:
- Introduces
OBI_TYPEDEF_MIN_WIDTH(WIDTH)to clamp zero widths to1. - Applies the clamp to ID and optional-signal widths in
OBI_TYPEDEF_*channel/optional typedef macros.
