How to Explain Your VLSI Project in a Technical Interview

“Tell me about your project” sounds like an easy question, but it can quickly turn into a deep technical discussion in a VLSI interview.An interviewer may start with a simple…

DRAM vs SRAM: Architecture and VLSI Design Differences

DRAM and SRAM are two of the most important memory technologies used in modern digital systems. Although both are types of random-access memory, their internal architectures are very different. That…

Ready-Valid Handshake Protocol Explained for RTL Engineers

When two RTL modules need to exchange data, simply connecting a data bus between them is not enough. The receiving module may not always be ready to accept data, while…

Synchronous FIFO vs. Asynchronous FIFO: Design Differences Explained

A FIFO (First-In, First-Out) is a commonly used data-storage structure in digital and RTL design. It temporarily stores data so that information written into the FIFO is read in the…

How to Design Safe Handshake Logic Between RTL Modules

Modern RTL designs rarely consist of one block doing everything. A typical SoC or digital system is divided into multiple modules, with each block responsible for a specific operation. One…

Signed vs Unsigned Data Types in SystemVerilog RTL

A SystemVerilog signal can contain exactly the same bits and still produce a completely different result depending on whether it is treated as signed or unsigned.That is one of the…

How to Avoid Inferred Latches in RTL Design

Writing RTL that synthesizes into the hardware you actually intended is one of the most important skills for a digital design engineer. A few lines of incomplete Verilog can be…

Combinational vs Sequential Logic in RTL: Practical Design Examples

One of the first decisions an RTL engineer makes while writing hardware description language code is surprisingly fundamental: Is this logic combinational or sequential?The distinction sounds simple. Combinational logic produces…

Blocking vs Non-Blocking Assignments in Verilog: When Should RTL Engineers Use Each?

When students begin learning Verilog, two operators often create more confusion than expected: = and

How Cloud-Based EDA Tools Are Changing Chip Design

The semiconductor industry has always relied on powerful computing resources to design, verify, and manufacture increasingly complex integrated circuits. From RTL simulation and logic synthesis to physical design and timing…

The Role of EDA Tools in Modern Semiconductor Development

Imagine designing a modern smartphone processor containing over 20 billion transistors using only a pen, paper, and manual calculations. It would take thousands of engineers decades to complete a single…
