Encounter Power Routing Flow

deeps

 Hi, 

 I am trying to create a Encounter based power routing flow, i need some suggestions as to the order of the commands that we can use, for example do we create the stripe first or the follow rails.

  I am creating the power routes in the below order

1> Create core Ring

2> Connect the core ring to the power pads 

3> Create ring for selected macros

4> Create Stripes (both Vertical & horizontl) for the core area

5> Create follow rails

       With this order when the follow are created some of the follow will be left open with-out connecting to stripes or the core ring (due to mincut via violations)

        But if i create the follow rails first & then the stripes it creates a lot of Mincut via violations.

   Would be help-full for me if some one suggest the way the power routes to be created with out creating any DRC violations.

 

thanks

deepak.

     Hi Suraj,

               Thanks for the replay,

                  I am trying to create a power routing flow using encounter capabilities,  so it would be helpful for me if you can share some details about the commands that you are using in your flow,

           Also please let me know about,

    • Quality of the power structure created, will they have many DRC violations
    • How do you handle or make sure the connectivity between the macro pins & the power stripes
    • How do you handle the creation of stripes in the narrow channels
    • How do you make sure that all the stripes area connected, because if there is any spacing violations are some rule violating then that stripe will be left open, how do you connect such un-connected stripes do you use "sroute" commans to connect all these unconnected stripes    

                

    thanks
