Fig-1. Transition with “set sys mode lec”. The cmd files that are run are called dofiles. Logical Equivalence Check flow diagram. Based on command. Command-Line LEC: lec –nogui Step 2. (Optional) LEC Command : set log file LEC_Lab1.log Step 3. From the GUI window, click on the icon . We are considering Conformal tool as a reference for the purpose of explaining the importance of LEC. Conformal Logic Equivalence Check Results: After running the design through Conformal, the results showed 661 non-equivalent points. PDF | In this paper we will explore how to use the Cadence Conformal LEC tool capabilities to verify different types of designs, based on the. Related Files : In this Lab, we ... Start Cadence Conformal LEC from GUI mode. The design example discussed in this white paper is from a real world debugging session by a GOF customer. There are various EDA tools for performing LEC, such as Synopsys Formality and Cadence Conformal. Run LEC in shell mode / script mode. identified by Cadence’s Conformal LEC tool. Conformal Lec Training Basic Advance – Ebook download as PDF File .pdf), Text File .txt) or view presentation slides online. Thus, the Conformal tool can continue the comparison on only the aborted compare points. I'd … The equivalence checker is then run which either verifles the equivalence of the two designs or helps in debugging by identifying the failing points, ports, and nets. In the case of aborted compare points, we can change the compare effort to a higher setting. Conformal lec run:-----In main dir, we can have startup file .conformal_lec (it can be in installation dir, home dir or current dir) that conformal will execute on startup. Read RTL Verilog design as Golden Model. To our surprise, using the Conformal Ultra together with the effort "complete " we managed to verify the majority of the design in one flat run. HI I have some problems about Cadence LEC Conformal after I run the comparison between RTL and Synthesis result. Linux Shell Command : lec& Don’t forget to start X-window before GUI mode. Cadence Conformal suite of tools contains a tool called Logic Equivalence Checker or LEC. The Conformal tool displays the completed run time and total memory used for the comparison. Conformal ® LEC Logic Equivalence Checker Basic Training Manual Verplex ™ Cadence Conformal Tutorial. Models have been loaded, can compare. Cadence Encounter Conformal Equivalence Checking User Guide (LEC) 3. LEC comprises of three steps as shown below: Setup Mode, Mapping Mode and Compare Mode. Failing points in the reference and implemented design can be viewed side by side in a schematic browser. It shows non-equivalence after running a full comparison but I don't know how to solve it since the schematic is too large to debug. Setup Log File. Automatically tries to map key points. User -manual-cadence Design Systems-Encounter Conformal Equivalence. Conformal Usage Model. In this presentation we will also discuss how to use the different Cadence Conformal LEC capabilities and what benefits they provide, describing numerous best-known-methods developed at Intel.
