to 0, it will bypass this step and if there is an issue with the pdn connection it will be flagged by LVSMatthew Guthaus

09/19/2021, 12:40 AMAnd I also want to ask, if my macro has power strip, should I insert core_macro_grid for my design? Like, should I insert it to stuff like sky130_sram_4kbyte_1rw1r_32x1024_8? I infact set FP_PDN_ENABLE_MACROS_GRID to 0 but the step in the figure is still performed. Not sure how to disable it

to 0 it will disable connecting the macros to the top level grid, but it will specify a macros grid without the connect statement so that pdngen doesn't draw vertical straps over your macros.Peijun Hou
