pub fn synthesized_holds(syn: &str) -> Option<Holds>Expand description
What a synthesized flat image needs of the device, from its synthesis report: the ALMs and DSP blocks its partitions’
estimates sum to, and the M20K blocks the fitter gives its memories (floorplan::Ram::m20k, every partition’s), not
its block memory bits over a block’s 20,480: a stack of blocks a power of two deep, and a byte-enabled block’s 32
bits, take more blocks than the bits do. None when the report gives no partition’s ALMs or DSP blocks.
