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 (ATPG) 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. Earlier we presented a tutorial on ATPG for Combinational Circuits. This tutorial focuses on ATPG for sequential circuits

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

This tutorial is in continuation with our previous tutorial on Genus Synthesis Without Constraints (Timing Constraints). The timing constraints are written in Synopsys Design Constraint (SDC) file. 1. Open the terminal and type csh 2. Source the cadence.cshrc. 3. In ASIC lab folder, make a new directory. In this, make design.v (in this example counter.v).

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

Logic Equivalence Checking is a very important step to be performed after synthesis step. This operation checks for similarity between the original code and the synthesis Netlist. This operation is important as the synthesis tool may trim or remove some unused and unconnected ports and redundant logics. The steps of performing Logic Equivalence Checking in

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
