The platform default BLOCKS_grid_strategy.tcl defines an ElementGrid macro grid with only an M5-M6 connection rule but no stripes, producing empty macro PDN grids. Use BLOCK_grid_strategy.tcl instead, which has M4-M5 connections matching the block's MAX_ROUTING_LAYER=M4 constraint. This is the same pattern used by aes-block (via block.mk).

@maliberty If this needs regeneration of the rules.json, could you do it? |
