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.

  • Hi  dbekiaris,

    Use this command for connecting stripes to Ram pins and let me know whether it solved your problem or provide more details about problem.

    editPowerVia -add_vias 1 -selected_blocks 1 -top_layer top_layer_name -bottom_layer  bottom_layer_name -orthogonal_only 1

    Thanks
