Struct VehicleMacro 

pub struct VehicleMacro {
    pub die_um: (f64, f64),
    pub hold_margin_ns: f64,
    pub grid: MacroGrid,
}

A macro hardened to sit INSIDE a shuttle vehicle’s wrapper — the Caravel user macro.

Its die is ours to choose, but its power nets and routing ceiling are the vehicle’s: it takes the harness’s supplies through power pins, and its routing ceiling follows from how the wrapper’s grid feeds it (MacroGrid).

Fields

die_um: (f64, f64)

hold_margin_ns: f64

Extra hold slack the macro closes every path to. The paths the wrapper would see violated start at a harness input port and end at a flop in here; the wrapper is a cell-free routing shell (cells in it need taps and fill, which broke its LVS: 0 -> 7,755 with input buffering), so they are closed on THIS side — by vehicle_macro_sdc, which holds the macro’s ports to the harness’s real minimum input delays. dram_user_project was hardened before that SDC existed and closed its 97 such paths (the pure shell ran hold -0.57 ns over them) with a 0.7 ns margin here; a margin that size applies to every internal path as well, which a macro with tens of thousands of flops cannot afford.

Trait Implementations

impl Clone for VehicleMacro

fn clone(&self) -> VehicleMacro

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VehicleMacro

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

Formats the value using the given formatter.

impl PartialEq for VehicleMacro

fn eq(&self, other: &VehicleMacro) -> 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.
