I've used create_library_domain+set_attribure avoid true... commands in RC to avoid instantiation of certain cells within a subdesign.Now I'm in Encounter. What is the best way to avoid optimization to replace cells and use those I didn't want?I've found some optionsa)setOptMode -noRestructb)set_dont_touch on cells I don't want it to be replaced(a) is not desirable because it's a global option and there are modules I'd like to let Encounter to optimize(b) is ok, but I would like to let Encounter optmize(resize, restructu) whenever needed but just not using some types of cells.Do you suggest any other option?Thanks.
No easy to undel that in Encounter...One possible workAround is to:1- Setup your restrictive dontUse list2- Run a full block optimization3- set a dontTouch on your specific module4- relax your dontUse list5- run incremental optimizationFor the step 2, you might have to specify a path_group (Someting available in 71), if your critical path is outside your special module, to force encounter to work for path within it.Pat.
