User -manual-cadence Design Systems-Encounter Conformal Equivalence. Linux Shell Command : lec& Don’t forget to start X-window before GUI mode. HI I have some problems about Cadence LEC Conformal after I run the comparison between RTL and Synthesis result. Fig-1. Failing points in the reference and implemented design can be viewed side by side in a schematic browser. 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. Cadence Conformal suite of tools contains a tool called Logic Equivalence Checker or LEC. 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. Conformal Lec Training Basic Advance – Ebook download as PDF File .pdf), Text File .txt) or view presentation slides online. Automatically tries to map key points. 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. In the case of aborted compare points, we can change the compare effort to a higher setting. From the GUI window, click on the icon . Conformal ® LEC Logic Equivalence Checker Basic Training Manual Verplex ™ Cadence Conformal Tutorial. (Optional) LEC Command : set log file LEC_Lab1.log Step 3. Thus, the Conformal tool can continue the comparison on only the aborted compare points. Setup Log File. Conformal Usage Model. The cmd files that are run are called dofiles. I'd … Related Files : In this Lab, we ... Start Cadence Conformal LEC from GUI mode. 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. Transition with “set sys mode lec”. Cadence Encounter Conformal Equivalence Checking User Guide (LEC) 3. Run LEC in shell mode / script mode. 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. Read RTL Verilog design as Golden Model. identified by Cadence’s Conformal LEC tool. Models have been loaded, can compare. Based on command. Logical Equivalence Check flow diagram. The design example discussed in this white paper is from a real world debugging session by a GOF customer. LEC comprises of three steps as shown below: Setup Mode, Mapping Mode and Compare Mode. Conformal Logic Equivalence Check Results: After running the design through Conformal, the results showed 661 non-equivalent points. We are considering Conformal tool as a reference for the purpose of explaining the importance of LEC. Command-Line LEC: lec –nogui Step 2. The Conformal tool displays the completed run time and total memory used for the comparison. There are various EDA tools for performing LEC, such as Synopsys Formality and Cadence Conformal. 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.
