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
