Let's Program the Transistors
This post contains some very interesting interview questions asked by Synopsys the EDA giant in its interview. The questions are based on Verilog Synthesis and Simulation. Though I have included the answers; I would encourage the reader to experiment himself or herself and then discuss these in the forum. 1. How a latch gets inferred…

Case and Conditional Statements are available in both VHDL and Verilog. These are considered as significant features of behavioral modelling, be it in VHDL or Verilog. Behavioral modelling provides high level abstraction so that the circuit can be designed by programming its functionality. Let’s say, we have to design a circuit that selects a particular…

Problem Statement: Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit. Pin Input / Output Description D Input Data Input CLK…

Flip-Flop (FF) and Latch are digital electronic circuits that are used to store information in bits as they have two stable states. One FF or latch can store 1 bit of information. FF is a circuit that can be made to change its state by applying signals to one or more control inputs and will have…
Combinational and Sequential circuits are the most essential concepts to be understood in digital electronics. Sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs. Combinational Logic Circuits Sequential Logic Circuits Output is a function of the…
