Hello, I was trying to make SAR logic. Is there some documentation about the sky_130 std cells? I got the dlrbn_1 working ( its a low gate -N latch if I'm correct? Whats the difference with the dlrbn_2? ) but I don't get the dfbbn_1 working , I assume it is a Dff? I got the results shown in attachement. In this setup Set-B is connected to ground, but I got the same general form when connected to vdd. But I'm not sure if it is active low or high.
the first to letters of the name are dl = Dlatch, and Df, D fliflip, I assume? What do the other letters represent?
Are these standart cells minimum sizes? Because if I look at the spice of the models, they seem sized hugely.
Have a nice day
