+-- Purpose: Regression multi tb for tb_lofar2_unb2c_sdp_station_bf
+-- Description:
+--   The multi tb only has one instance, so the tb_tb is more a wrapper to
+--   ensure that always the same tb generics are used in the regression test.
+--   This allows modifying the generics in the tb.
+-- Usage:
+-- > as 4
+-- > run -all
