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.

  • Hello kari I post a picture from the block ring I try to connect to, through the Add Stripes wizard. I suppose that the problem is with the macro block, because the stripes are on the same metal layer with the power/ground of the macro. However, they can not be connected, even if I try other options (ommit stripes over block rings and omit stripes over selected blocks/fences/domains). Can you extract anything from this picture ? Please advise! Thank you very much in advance. Kind regards
