Managing Miniatures: Techniques to manage OCV in VLSI Design

Built in self test in vlsi

As technology miniaturizes, pushing the boundaries of materials and design, On-Chip Variation (OCV) plays a crucial role in VLSI design. By simulating variations within chips, OCV helps prevent malfunctions after fabrication, ensuring functionality in increasingly compact sizes. This becomes especially critical with initiatives like India’s proposed semiconductor plants, highlighting the need for advanced VLSI techniques […]

What Is The Threshold Voltage?

Threshold Voltage

In the realm of VLSI (Very Large Scale Integration), threshold voltage holds immense significance as a critical parameter that governs the behavior of MOSFETS (Metal-Oxide-Semiconductor Field-Effect Transistors). These tiny transistors serve as the building blocks of integrated circuits, forming the foundation of modern electronics. Threshold Voltage: The Gatekeeper of Current Flow The threshold voltage, often […]

Steps In VLSI Physical Design Flow

Physical design flow

Steps in VLSI Physical Design Flow VLSI physical design flow is a cardinal process of converting synthesized netlist, design curtailment, and standard library to a layout as per the design rules. This layout is further sent to the foundry for the creation of the chip.   According to an article on Times of India, we […]

Power Of Chiplets In The Semiconductor Industry


Korea Times published an article recently, in which it stated that ‘Chiplets have emerged as a catalyst and are reshaping the global semiconductor industry’. The article also says how Huawei, a Chinese multinational technology corporation, has embraced chiplet technology and cultivated a self-reliant, and robust supply chain.  What are Chiplets? Chiplets are individual semiconductor components […]

What is Crosstalk in VLSI and its Impact on 7nm Technology?

Crosstalk in VLSI

As we progress through the lower technology nodes of IC (integrated circuit) design, semiconductor designs get more complex. By scaling the technology node, many parameters, such as the width of metal wires and transistor size, tend to be downscaled. In terms of routing resources, 7nm designs are denser than the preceding nodes. As a result, […]

Analog layout design is a critical aspect of integrated circuit creation, and preparing for these interviews is vital to your success. […]

All You Need to Know About Netlist in VLSI!

Netlist in VLSI

Netlist contains the electrical connections between the components on the circuit board and is usually held in a textual format. In an electronic circuit netlist is the description of the connectivity of an electronic circuit it contains the list of all the electronic components in a circuit and the nodes they are connected to circuits. […]

What Is Routing In VLSI Physical Design?

Routing in VLSI is making physical connections between signal pins using metal layers. Following Clock Tree Synthesis (CTS) and optimization, the routing step determines the exact pathways for interconnecting standard cells, macros, and I/O pins. The layout creates electrical connections using metals and vias that are determined by the logical connections in the netlist (i.e; […]

What Is The Antenna Effect in VLSI?

The most sensitive component of a MOS transistor is the gate oxide. During the construction of an ASIC, special care must be taken to safeguard it from damage both throughout the fabrication process and during the functioning of the ASIC. Some unwanted impacts can arise throughout an actual manufacturing process. The antenna effect in VLSI, […]
