pub fn place_unrolled(
mp: &Metapipeline,

t: &PlasticineTarget,

) -> Result<Placement, Unplaceable>Expand description
Allocate mp (with ag_stages on the perimeter address generators) once, unroll it par ways, and
place every instance — a typed TooSmall when the replicated allocation exceeds the mesh.
