Hello, I have a problem with macros. Could you help me? I've tried many things for about 15-20 hours. I'm desperate. I just want to connect two macro cells together in another cell without a grid. Do you know how to do that and what configuration I need? The LEF file, the GDS, and Verilog as a black box have been put correctly. You can see my GDS file here

You want to abut the 2 macros so that they connect without wiring? I don’t know that openlane can do that. You might try creating a new macro consisting of the 2 macros placed so that they are connecting. Might need to add another verilog stub to join them. On the layout side, make sure the there’s text and a corresponding shape at each of the pins.

For example, a connection like that. Here, there is no grid.

Ok. I think what you’re referring to as the grid is the power routing. You can turn off the power grid in the config file.

Yes, sorry, I misspoke when talking about the power grid. I tried to remove it without success. I set FP_PDN_ENABLE_RAILS to 0 and tried many other combinations, but I can't remove the metal1 grid (VDD and VSS).

Did you try

"FP_PDN_MULTILAYER": false,

? What about using

FP_PDN_CFG

and then defining a routing that doesn’t do anything.

I finally did it; there's no met1 power grid. The next step is to connect VSS and VDD, I can't do that know...
