pub fn target_for_mesh(rows: usize, cols: usize) -> Option<PlasticineTarget>Expand description
The descriptor a toolchain row’s rows × cols mesh calibrates against: the 20x20 mesh is PIR’s default in
front of Tungsten’s DDR4 memory (PlasticineTarget::tungsten_20x20_ddr4, the system the chain simulates);
the 16x8 mesh is the ISCA’17 preset.
