Hard macros power routing issues

dbekiaris

Hello everybody,

 I import a design in SoC Encounter 7.1, where three hard macros (SRAMs) exist. The problem is that when I am trying to create the power stripes and connect them with the core rings to synthesize the power grid, the SRAM p/g pins cannot connect with the remaining power/ground network, although I have selected the proper metal layer from the .lef files of the macros. Is there anything possible to do for this? I tried also to align pins of the specified macros with the power/ground stripes, but it failed again. If it is possible, please help. Thank you very much in advance.

  •  Can you zoom in more closely to the corner of that macro, so that I can see the macro corner, one or two of your stripes, the ring around the macro, and the macro pins? It is still difficult to tell what you're trying to do. It also still sounds like you're expecting addStripe to connect your block pins, which is not the use model. You will need to use Sroute to connect block pins outward to a stripe or ring.
