- Changed parameter names in various modules from uppercase to camel case for consistency. - Updated local parameters in testbenches to follow the same naming convention. - Modified the RTL style manifest to include additional prefixes for better organization. - Enhanced the check_format and check_rtl_style scripts to improve file tracking and naming validation. - Added new tests to ensure compliance with the updated naming conventions and allowed local parameters in specific contexts.
