Synthesis in VLSI

Posted on November 18, 2019June 17, 2025 By Dewansh No Comments on Synthesis in VLSI

Synthesis transforms the simple RTL design into a gate-level netlist with all the constraints as specified by the designer. In simple language, Synthesis is a process that converts the abstract form of design to a properly implemented chip in terms of logic gates. Synthesis takes place in multiple steps: There are various tools which can…

Getting started with TLM 2.0 – Introduction and Basic Constructs

Posted on August 18, 2016June 17, 2025 By Dewansh No Comments on Getting started with TLM 2.0 – Introduction and Basic Constructs

The TLM 2.0 transaction level modeling standard from the Open SystemC Initiative (OSCI) was released on 9th June 2008. Transaction-level modeling (TLM) is a high-level modern approach to modeling digital systems. That modeling is based on the abstraction of the communications between different parts of the model to allow to work the algorithms of each…

What is TLM-1 and what was the need for TLM 2.0?

Posted on August 17, 2016June 17, 2025 By Dewansh No Comments on What is TLM-1 and what was the need for TLM 2.0?

Transaction-level modeling (TLM) is a high-level modern approach for modeling digital systems. TLM-1 standard defined a set of interfaces which could be used for transporting transaction by value or reference. TLM-1 is being used successfully in some applications but it had shortcomings which have now been improved upon in TLM 2.0. TLM-1 has no standard…

FPGA vs. Microcontroller

Posted on March 13, 2016June 17, 2025 By Dewansh No Comments on FPGA vs. Microcontroller

FPGA stands for Field Programmable Gate Array. They are programmable integrated circuits made up of a large number configurable logic blocks (CLBs), fixed function blocks and memory blocks which can be used to perform complex digital computations. The CLBs are the basic and most important unit of FPGA. CLBs are made up of Look Up…

Difference between Combinational and Sequential logic circuits.

Posted on October 27, 2015June 16, 2025 By Dewansh 24 Comments on Difference between Combinational and Sequential logic circuits.

Combinational and Sequential circuits are the most essential concepts to be understood in digital electronics. Sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs. Combinational Logic Circuits Sequential Logic Circuits Output is a function of the…
