Does encounter optmizes ideal net when optdesign command is given.

gops

In new version of encounter there is no provision to give exclude nets while loading design. But I have set_ideal_net in my SDC, a reset net which I want to do buffer tree synthesis. But while doing optdesign after placedesign, I found encounter buffering those ideal_nets. How can i solve this issue. 

  • if you don't want optDesign to buffer that net, make the net set_dont_touch.

    set_dont_touchobject_list[true | false]

    Prevents the specified object from being modified during optimization.

    When you specify a net, all the connecting instances are affected by the set_dont_touch command.
