WebMar 1, 2012 · In nanometer-scale VLSI physical design, clock tree becomes a major concern on determining the total performance of the chip. Both the clock skew and the PVT (process, voltage and temperature) variations contribute a lot to the behavior of the digital circuits. Previous works mainly focused on skew and wirelength minimization. WebJun 10, 2015 · For your counters the left most two digits are going to 00, so you detect that with gates or whatever, then load at least the one counter with "1", so you end up with 01 in the left most two digits. That gives you the time display of one o'clock which would look like 01:00 on your display, instead of 00:00 which you seem to have now.
