As we know that cell delay is a function of output load capacitance. The most simplistic equivalent circuit of a logic gate driving an out...

Clock dividers are ubiquitous circuits used in every digital design. A divide-by-N divider produces a clock that is N times lesser frequen...

Problem: 100 latches (either all positive or all negative) are placed in series (figure 1). How many cycles of latency will it introduce?...

VLSI stands for Very Large Scale Integration and it enables the creation of integrated circuits by incorporating thousands, and even milli...

‘X’ refers to a signal attaining a value that is ‘unknown’. It can be either ‘0’ or ‘1’. But, the exact value of the signal is not known...

As we discussed in ‘’ Is it possible for a logic gate to have negative propagation delay ”, a logic cell can have negative propagation de...

Hexadecimal to decimal conversion is something that is often needed in hardware. Below functions can be used for hexadecimal to decimal con...

Problem: Can you figure out what is wrong with following piece of code? #include <iostream> int main() {       int a[5] = {1,...

Definition of multicycle paths : By definition, a multi-cycle path is one in which data launched from one flop is allowed (through archi...

Three variable  function can be easily implemented using 8:1 multiplexer. connect 3 input lines to select lines of mux and connect 8 in...
