06.10.2021 · Under such conditions, the design is subjected to logical equivalence checking (LEC), where the tool validates the design by injecting random vectors. There are numerous tools available in the industry to check logical equivalence, but the most widely used ones are Conformal from Cadence and Formality from Synopsys.

If RTL is the golden, write_do_lec will write out a hierarchical compare script, unless you explicitly say -flat. Similarly, if you are generating a dofile with write_do_lec and you specify a -golden netlist (such as in the intermediate-to-final comparison), write_do_lec will default to writing a flat compare script.
