1. Harden your design/macro without using metal5
2. And use vertical straps of metal4 in your macro for power, dont use horizontal straps
3. When inserting the macro in userwrapper, block met1/2/3/4 for macro in pdn.tcl
4. Horizontal straps of user wrapper would then overlap the macro placing vias for power connection.

11/07/2021, 4:43 PMseems that worked just limiting the number of layers to 4 (in fact the default value is 5 for the user project example)
