    keyword=Retiming check bis

    Looked with scope, retiming seems OK.

    I tried a few runs with different delays on L1A but it is a bit hard to conclude with low statistics of cosmics.

    Just took a run with T3 and T4 only it looks good.

    Only things which I know have changed and they should not have influenced the retiming since L1A seemed to always arrive before retiming signal : - we delayed and reduced width of OR of S2m so it fits well in S1 or, now S2m or is about 50 ns and arrives 25 ns after S1 or. - Miha removed a delay module on the trigger going to the trigger supervisor

    Though a whole bunch of cable were moved around so that can be it too.

    I noticed the N_I input at the TM module is a bit loose. I think it is better to leave the short cable in it and use the other end of the cable rather than unplugging it from N_I

    So this looks good enough to me. Smaller number of triggers are T4
