Indeed, even with well-written constrained-random testbenches, simulation may find functional differences depending on the quality of the testbenches but such analysis could still miss critical corner cases. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. In this session, you will how to use SLEC to verify that the design works the same with and without added low power clock gating logic. Fast root-cause analysis of failure points, Comprehensive clock-gating verification coverage-based signoff process, including automatic clock gating coverage analysis, Confirming that dynamic power optimizations (such as clock gating) were inserted correctly, Verifying that an algorithmic change or performance optimization in the RTL didn't break the desired functionality, Validating an engineering change order (ECO), Ability to prove that two designs expressed in RTL exhibit the exact same behavior at sequential design points, Special optimized engines for SEC that exhibit superior performance compared with other conventional formal tools. Find all the methodology you need in this comprehensive and vast collection. No one argues that the challenges of verification are growing exponentially. Please confirm to enroll for subscription! Other- wise, the two circuits are proved sequentially equivalent. The app delivers superior results for the equivalence problem when compared with other conventional formal tools. Instead of relying on test benches or properties, sequential equivalence checking uses a golden RTL model or system-level reference design written in Verilog, VHDL, SystemC or C/C++. What is needed to meet these challenges are tools, methodologies and processes that can help you transform your verification environment. The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Unlike attempting to use simulation-based approaches or adapting regular formal tools for this type of verification, the JasperGold SEC App provides a special formal engine optimized for exhaustively verifying SEC problems. In this session, you will learn how to use SLEC to verify that bug fix/ ECO doesn’t introduce new bugs. Sequential Equivalence Checking opens up possibilities in this area, by enabling performance-tuning related sequential micro-architectural changes to be verified with significantly lower impact on effort estimates and risk.

Cadence® system design and verification solutions, integrated under our Verification Suite, provide the simulation, acceleration, emulation, and management capabilities. Designed with high-productivity workflows, the Cadence® JasperGold® Sequential Equivalence Checking (SEC) App is a formal verification product that inputs two register-transfer level (RTL) models and verifies their sequential behavioral equivalence. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. We encourage you to take an active role in the Forums by answering and commenting to any questions that you are able to. These topics are industry standards that all design and verification engineers should recognize. These recorded seminars from Verification Academy trainers and users provide examples for adoption of new technologies and how to evolve your verification process. As such, SLEC can save a lot of resimulation time after small modifications of the design. Thank you for subscribing. This nascent technology promises to change the way we look at eleventh hour changes. There are many cases when you need to verify the sequential equivalency of two different RTL circuit descriptions. The Verification Academy Patterns Library contains a collection of solutions to many of today's verification problems. SLEC’s effectiveness comes from using exhaustive formal verification algorithms, which do not require a testbench; and indeed are completely automated so the user does not need to know about formal technology themselves. An Introduction to Unit Testing with SVUnit, Testbench Co-Emulation: SystemC & TLM-2.0, Formal-Based Technology: Automatic Formal Solutions, Getting Started with Formal-Based Technology, Handling Inconclusive Assertions in Formal Verification, Whitepaper - Taking Reuse to the Next Level, Verification Horizons - The Verification Academy Patterns Library, Testbench Acceleration through Co-Emulation, UVM Connect - SV-SystemC interoperability, Debug with Codelink and Visualizer - December 8th, I'm Excited About Formal...My Journey From Skeptic To Believer, Improving Your SystemVerilog & UVM Skills, Questa Simulation Coverage Acceleration Apps with inFact. In this course, you will be introduced to the concept of sequential logic equivalence checking and its common applications. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests. In this session, you will learn the concept of sequential logic equivalence checking (SLEC) and the common applications of SLEC. It is also very efficient in verifying safety mechanisms used in ISO 26262 and other fault mitigating designs. The risk is exacerbated when the circuit(s) implement clock-gating schemes, since clock gating is notorious for its ability to conceal corner-case bugs and functional mismatches. The. If an output of the miter can ever become 1, sequential equivalence is violated, and model checking can provide an input sequence leading to the violation. You will also learn how to start with Questa® SLEC to verify design optimization, bug fix/ECOs, low power clock gating logic, and safety mechanisms. In this session, you will learn how to use SLEC to verify functional equivalence between two RTL designs before and after optimization. The Verification Academy offers users multiple entry points to find the information they need. The patterns contained in the library span across the entire domain of verification (i.e., from specification to methodology to implementation—and across multiple verification engines such as formal, simulation, and emulation). © 2020 Cadence Design Systems, Inc. All Rights Reserved. Cadence® system analysis solutions provide highly accurate electromagnetic extraction and simulation analysis to ensure your system works under wide-ranging operating conditions. The app also has a customized GUI specially structured to highlight functional differences discovered between the specification and implementation RTL. Driving efficiency and accuracy in advanced packaging, system planning, and multi-fabric interoperability, Cadence® package implementation products deliver the automation and accuracy. Cadence® PCB design solutions enable shorter, more predictable design cycles with greater integration of component design and system-level simulation for a constraint-driven flow. Sequential logic equivalence checking (SLEC) is effective in finding bugs in new logic required to reduce dynamic power consumption, validating last minute ECOs, or verifying that design optimizations aren’t too aggressive. In contrast, simulation-based approaches cannot prove sequential equivalence. The Verification Community is eager to answer your UVM, SystemVerilog and Coverage related questions. Watch how to easily tackle complex and cutting edge designs. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers. Cadence® custom, analog, and RF design solutions can help you save time by automating many routine tasks, from block-level and mixed-signal simulation to routing and library characterization. Given the formal-based nature of the analysis, SLEC can prove functional equivalence of the two designs for all inputs and all time, or identify any differences between the two designs. Sequential Equivalence Checking •Represent each sequential circuit as an FSM –verify if two FSMs are equivalent •Approach 1: Reduction to combinational circuit –unroll FSM over n time frames (flatten the design) M(t 1) x(1) s(1) M(t 2 x(2) s(2) … … n) x(n) s(n) Combinational logic: F(x(1,2, …n), s(1,2, … n)) – check equivalence of the resulting combinational circuits Gui specially structured to highlight functional differences discovered between the specification and implementation RTL open IP platform you!
