We already discussed why designers need to do LEC, and we will talk about Conformal LEC flow in this post.
In LEC setup, there are several steps that designers need to follow:
- Read and elaborate reference design
- Read and elaborate revised design
- Specify “notranslate modules” for blackboxing if the module is a macro, or the module has been LECed in block level
- Set certain constraints, for example, when comparing between RTL and synthesis netlist, set case analysis to ignore scan ports
