Enum MacroGrid 

pub enum MacroGrid {
    Own,
    WrapperFed,
}

How a vehicle user macro takes power from the wrapper around it, which decides how high it may route.

The wrapper’s grid generator keeps its straps off a macro’s obstructions and feeds the macro’s own power pins where the two cross. MEASURED (wrapper PDN spike, 2026-09-26: the DRAM wrapper around a copy of its macro’s abstract with the met5 power ports removed and met4 obstructed across the die): every supply’s met4 straps were cut at the macro — 0 of 257 segments over it, against 127 over the unmodified macro (RUN_2026.09.23_12.53.02) — and met5 crossed it and fed vccd1 and vssd1 through 190 via stacks each.

Variants

Own

Its own grid, as a core: straps on both of the process’s PDN layers, and routing below them (UserArea::macro_max_layer); the wrapper’s grid passes over it on both layers.

WrapperFed

Straps on the vertical PDN layer only, crossed and fed by the wrapper’s horizontal straps, and routing up to that layer (UserArea::fed_macro_max_layer); the wrapper’s vertical straps stop at the macro. efabless’s reference user macro.

Implementations

impl MacroGrid

pub fn parse(s: &str) -> Option<MacroGrid>

own / fed.

pub fn flag(&self) -> &'static str

The flag spelling MacroGrid::parse reads back.

Trait Implementations

impl Clone for MacroGrid

fn clone(&self) -> MacroGrid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MacroGrid

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MacroGrid

fn eq(&self, other: &MacroGrid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
