Function mcast_corners 

Source 
pub fn mcast_corners(
    p: &SpatialProgram,
    site: Site,
    operand: Operand,
    noc: u8,
) -> Result<((u16, u16), (u16, u16)), SpatialLowerError>
Expand description

The multicast rectangle of a site’s receivers for operand, as (start, end) corners for a kernel on noc: NOC 0 travels toward larger coordinates and takes the near corner first; NOC 1 travels the other way and takes the far corner first (the vendor’s right → left+1, bottom → top+1). The simulator refuses a rectangle given against its NOC’s direction.
