In the previous tutorials, we have seen how to use Cadence INNOVUS GUI for placement and routing. But INNOVUS tool works better when used with scripts. It is convenient to use the script based placement and routing as numerous runs are needed to successfully verify an IC. This is also the industrial practice. In this […]

In the previous three tutorials, we have learned how prepare the files which are needed to start the placement and routing using INNOVUS. In this tutorial, a basic tutorial on how to perform placement and routing using INNOVUS is given. This is a very fundamental and only covers the basic ideas and follows the tutorial

In the previous tutorial on Placement and Routing using INNOVUS, we have seen how to open the tool and how to import all the files. In this tutorial, we will discuss how to prepare view definition file by performing Multi Mode Multi Corner (MMMC) analysis. MMMC analysis is very important to perform, so that the

In the previous tutorial, we have presented a basic tutorial on Placement and Routing for ASIC. This tutorial is the first step towards Placement and Routing using INNOVUS tool. We will cover very basics of Placement and Routing using INNOVUS as it is a huge area and many tutorials are available on internet. Here, we

The previous tutorials [Tutorial 1, Tutorial 2] are on the simulation and synthesis of Verilog files. In addition to these we have also performed linting, code coverage, logic equivalence check, DFT, ATPG, power analysis and Timing analysis using CADENCE and SYNOPSYS tools. Till now we have not discussed anything about the step Placement and Routing

Synopsys Simulation and Synthesis ATPG for Combinational Circuits ATPG for Sequential circuits Power Analysis using Synopsys 00
In the previous tutorials, simulation and synthesis of digital circuits are described. This tutorial is on Power Analysis using Synopsys. Here, dynamic power consumption of a sequential circuit is estimated. 1. Open the terminal 2. Source the synopsys.cshrc 3. In this experiment, we perform power analysis (dynamic power) of the design using power compiler. 4.

Automatic Test Pattern Generation and Automatic Test Pattern Generator (ATPGA) is an electronic design automation method/technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects. This tutorial focuses on ATPG for combinational circuits using Synopsys Tetramax tool. 1. Open the terminal 2. Source

Here, we will discuss the tutorials on how to synthesize a Verilog code starting from simulation, syntax checking, code coverage using CADENCE EDA tool. Basic Simulation on CADENCE Linting Code Coverage Logic Equivalence Check Genus Synthesis without Constraints Genus Synthesis with Constraints Genus Synthesis using Scripts Static Timing Analysis using Cadence Tempus +20
In our earlier tutorials [GENUS Synthesis With Constraints, GENUS Synthesis Without Constraints] on synthesis of Verilog files using Cadence Genus tool, we have seen how synthesis can be performed with or without timing constraints. But it is very painful to perform synthesis operation by executing commands one by one in the command prompt. Thus industry

In this tutorial Cadence GENUS Synthesis without Constraints is presented. 1. Open the terminal and type csh 2. Source the cadence.cshrc. After sourcing the file, check whether genus is installed in the current system or not by typing the below command [sudi@sankh] genus –gui 7. Minimize the gui and follow below instructions, mentioning the proper

Code coverage is a basic coverage type which is collected automatically. It tells you how well your HDL code has been exercised by your test bench. In other words, how thoroughly the design has been executed by the simulator using the tests used in the regression. Functional coverage measures how well the functionality of the
Linting is a process of running a program that will analysis the code for potential errors. This tutorial is for checking errors and warnings in a Verilog code using Cadence tool. Open the terminal Source the cadence.cshrc In a new ASIC lab directory, write a Verilog coded design (in this example fifo.v) Write the linting
