EDA tools for VLSI design

What is EDA (VLSI CAD)?

Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. CAD programs specific to the electronics industry are known as electronic CAD (ECAD) or electronic design automation (EDA).

 


EDA tools help to create and program multiple types of electronic circuits like an integrated circuit (IC), printed circuit board (PCB) and system on chip (SoC).It uses multiple features like logical design, circuit schematic design, layout generation, design simulation and many more features for VSLI design.

To enter a design into an EDA tool, a suitable design entry method is required. Typically, tools will allow the following design entry methods:

1.Circuit schematics present a graphical view of the design using logic gate symbols and interconnect wiring.

2.Boolean Expressions can be entered as a text-based description in combinational logic designs.

3.HDL design entry allows a description of the digital logic circuits or system operation to be entered in text form using a suitable language.

4.State transition diagrams present a graphical view of state machines that identifies the design states and the transitions between states.

The availability of a particular design entry method depends on the EDA tool used.


EDA tools in VLSI

EDA’s big three:

  • Synopsys
  • Cadence 
  • Mentor Graphics

Other Software tools: Xilinx, Keysight ADS, Keysight IC-Cap, Silvaco TCAD 3D, Silvaco AMS, GTS TCAD Framework and QuantumWise ATK.

EDA tool for VLSI with License:

In the industrial environment, Cadence virtuoso, Synopsys, and Mentor Graphics are mostly used. To use these software’s you have to purchase the license as they are not open source. These are expensive in cost.

Open-Source EDA tool for VLSI:

For learning purposes, you can use open-source software tools like Electric, Alliance, Glade. You don’t need to pay for them. You can download them free of cost.

In this blog we will understand the various IC design components and open source tools available to perform IC design. First lets take a look at  IC design components.  Fig: Logic Synthesis First step in IC design is to do Logic Synthesis . Logic synthesis is a process by which an abstract specification of desired circuit behavior which is the netlist, at register transfer level (RTL), is converted or transformed into a design implementation in terms of logic gates. And the open source tool which helps us do logic synthesis is Yosys Open Synthesis Tool . Fig: Floor-planning Second step is Floorplanning . In floorplanning blocks/macros in the chip/core area, are placed . Floor-plan determines the size of die and creates wire tracks for placement of standard cells. It. creates power ground(PG) connections.           Fig : Placement and Clock Tree Synthesis Third Step is Placement of logical cells that we got from first step and third step is CTS Clock...
