<mithro> Anyone know what the B in a DFB where `DF` stands for D-flip-flop -- I think it means that the D-flipflop has a set/reset signals
<tnt> where did you see that ?

<mithro> tnt: In the name for a primitive definition
<mithro> The verilog table is like this -> https://www.irccloud.com/pastebin/AoZmFbWH/
<tnt> I know there is an old convention with B="Async Preset" D="Async Clear" I="Sync Clear" J="Sync preset"

<mithro> This code does come from like 2000ish...
<tnt> Could also be like lattice where A B C D E ... are just revisions of the model/primitive :p

<mithro> SB in the name seems to indicate an async set
gnufan has joined ##openfpga
<daveshah> Are there other DFF primitives that don't end in B?

<mithro> @daveshah Yeah, most of them are like DF_N_S_R and DF_P_R etc....
<mithro> first N/P after the DF is the clock edge
mumptai_ has quit [Quit: Verlassend]
<daveshah> Seems very random then
mumptai has joined ##openfpga
<daveshah> I suspect B might just be some variant of the cell, as tnt suggested
<daveshah> With the original ones being "A" implictly
