We are using conformal software Version 7.1 to perform LEC check. we used netlists ( VQM ) to compare the Logic equivalences. Both the netlists are generated using synplify tool. When compared between these two netlists we could see warnings Unmapped points due to DLAT's ( D LATCHES ). Few among the warning messages are extracted and shown below.

LEC is significant for the designers who need to compare the synthesis netlist with RTL. The most common LEC tools include Cadence Conformal ...

06.10.2021 · Figure 1 A typical Conformal LEC flow comprises a setup mode and an LEC mode. A typical conformal LEC flat run flow mainly consists of a setup phase followed by a LEC mode. The setup mode consists of the following steps: Specification of blackbox Reading libraries and designs Specification of design constraints Specification of modeling directives
