Compilation, Elaboration, and Simulation in HDL: A Clear Guide with Examples

July 21, 2025July 18, 2025 vlsifacts No Comments

When working with Hardware Description Languages (HDLs) such as Verilog or VHDL, understanding the design flow is crucial for successful digital circuit development. Three fundamental steps in this flow are Compilation, Elaboration, and Simulation. These steps ensure that your HDL code is syntactically correct, logically consistent, and behaves as expected before hardware implementation. In this article, we will…

Loops are essential tools in Verilog for automating repetitive tasks, but not all loops are created equal when it comes to synthesizability and practical use. Among the various loop constructs, the while loop often raises questions because of its dynamic nature. In this blog post, we’ll explore the best use cases for the while loop in Verilog, why it’s…
