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. In this session, you will learn how to use SLEC to verify functional equivalence between two RTL designs before and after optimization. We encourage you to take an active role in the Forums by answering and commenting to any questions that you are able to. 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. 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. 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. 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. Easy validation of local or global RTL changes that exhibit design behaviors not verifiable by combinational equivalence checking tools, such as power/area optimizations, retiming changes, etc. 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. Unlike combinational equivalence checkers, sequential checkers prove functional equivalence across levels of sequential and data abstraction. Please confirm to enroll for subscription! 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 that the design’s safety mechanism handles faults as required. 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. In contrast, simulation-based approaches cannot prove sequential equivalence. An open IP platform for you to customize your app-driven SoC design. 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. Driving efficiency and accuracy in advanced packaging, system planning, and multi-fabric interoperability, Cadence® package implementation products deliver the automation and accuracy. The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. No one argues that the challenges of verification are growing exponentially. 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. It is also very efficient in verifying safety mechanisms used in ISO 26262 and other fault mitigating designs. The Verification Community is eager to answer your UVM, SystemVerilog and Coverage related questions. Watch how to easily tackle complex and cutting edge designs. 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. 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++. 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. These recorded seminars from Verification Academy trainers and users provide examples for adoption of new technologies and how to evolve your verification process. Thank you for subscribing. 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. However, due to the P-SPACE complexity of model checking, applying this to SEC problems may be too hard. It is also very efficient in verifying safety mechanisms used in ISO 26262 and other fault mitigating designs. 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. The app delivers superior results for the equivalence problem when compared with other conventional formal tools. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. 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. You will get an email to confirm your subscription. Cadence® digital design and signoff solutions provide a fast path to design closure and better predictability, helping you meet your power, performance, and area (PPA) targets. There are many cases when you need to verify the sequential equivalency of two different RTL circuit descriptions. This nascent technology promises to change the way we look at eleventh hour changes. The app delivers superior results for the equivalence problem when compared with other conventional formal tools. The Verification Academy Patterns Library contains a collection of solutions to many of today's verification problems. Find all the methodology you need in this comprehensive and vast collection. The Verification Academy offers users multiple entry points to find the information they need. 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. The app also has a customized GUI specially structured to highlight functional differences discovered between the specification and implementation RTL.
