Understanding Reset Signals in Digital Design: Types, Pros & Cons, and Best Practices

June 30, 2025June 30, 2025 vlsifacts No Comments

In digital design, the reset signal is one of the most fundamental control signals. It ensures that your digital circuits start in a known, stable state before normal operation begins. Whether you’re designing a simple flip-flop or a complex processor, understanding resets is crucial for reliable and predictable behavior. In this post, we’ll explore: Why Do We…

1. Explain the concept of sensitivity lists in Verilog. A sensitivity list specifies the signals that trigger the execution of an always block when they change. Example: Here, the block executes whenever a or b changes. 2. What is the purpose of generate statements in Verilog? The generate statement is used to dynamically create repetitive hardware structures or conditional instantiations during elaboration. Example: 3. Discuss…

Case and Conditional Statements Synthesis CAUTION !!!

November 12, 2015June 16, 2025 Priyadarshi 5 Comments

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…
