Sanity Checks In VLSI: Better Vision For Better Connection

Sanity checks in VLSI are an essential step for physical design engineers to ensure that the inputs are proper and consistent. Any errors in the input files may cause trouble later on. Hence, it is critical to perform sanity checks early on, before loading the design into the PnR tool and before starting the floor […]

Macro In VLSI

VLSI, or Very Large-Scale Integration, embeds thousands of transistors into a single chip in an Integrated Circuit. Macro is an essential component in the VLSI design cycle before the final packaged chip is ready to use. Macro cells are the memory cells, intellectual property which an analog design team has designed. To break down the […]

What is Floor Planning in VLSI

The VLSI era of Integrated Circuits (IC) began in the 1970s when thousands of transistors were integrated into a single chip. More than a billion transistors can now be integrated into a single device. With the rapid advancement in chip development, design complexity has increased rapidly, and the number of transistors in a chip has […]

What is ECO in VLSI Physical Design?

Engineering Change Order or ECO in VLSI is the practice of introducing logic directly into the gate level netlist corresponding to a change that happens in the RTL. This owes to design mistake repairs or a change request from the customer. Engineering Change Order or ECO in VLSI is used to accommodate last-minute design revisions. […]

What is Clock Domain Crossing (CDC) and How Does it Work?

In digital electrical design, the process of moving a signal or vector (multi bit signal) from one clock domain to another clock domain is called clock domain crossing.  It is the traversal of a signal in a synchronous digital circuit from one clock domain to another. A digital circuit containing flip flops is generally related […]

Learn All About Logic Synthesis

In computer engineering, logic synthesis is the process of converting an abstract specification of desired circuit behaviour, often at the register transfer level (RTL), into a design implementation in terms of logic gates, typically using a synthesis tool, which is a computer software. This procedure comprises the synthesis of HDLs such as VHDL and Verilog. […]

How to choose Frontend vs. Backend?

VLSI frontend vs backend are nothing but two different domains in the field of VLSI. Frontend vs Backend, the classification is based on the different steps involved in a typical ASIC design flow. Following diagram shows a typical design flow for an ASIC or SOC. As it shows the design flow starts with a specification […]

What Are The Responsibilities Of A Physical Design Engineer In VLSI?

VLSI stands for very large scale integration which offers a diverse range of professional paths and prospects. The physical design engineers’ responsibilities include a wide range of tasks. Physical Design, often known as integrated circuit layout, is abbreviated as PD. It is one of the important parts of VLSI. Physical Design is a procedure that […]

Congestion in VLSI Physical Design Flow

As the number of transistors on a device grows, so does the design complexity. As a result, physical design plays a critical part in the VLSI design flow. When the number of routing tracks available for routing in a given location is less than the number necessary, the area is considered congested and hence, is […]

Job Prospects in VLSI Physical Design

VLSI provides a wide arena for career growth and opportunities. One of the main fields in VLSI is VLSI Physical Design. PD requires technical and practical knowledge on various subject matters. The industry is constantly growing and the job prospects in the PD field are many in number. What is VLSI Physical Design As the […]
