Cadence tutorial

Placement and Routing for ASIC

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 …

GENUS Synthesis using SCRIPTS

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 …

GENUS Synthesis With Constraints

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). …

Code Coverage

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

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 …
