ID:20807 Automatic Gated Clock Conversion is enabled, but no clocks are explicitly identified and this family does not support automatic clock recognition during synthesis. Add GATED_CLOCK_CONVERSION_BASE_CLOCK assignments to properly identify base clocks.

CAUSE: Gated clock conversion is enabled but this family does not support automatic clock recognition during synthesis and no clocks are identified.

ACTION: Explicitly identify base clocks for gated clock conversion using the "Gated Clock Conversion Base Clock" assignment.
