nlutmap - map to LUTs of different sizes¶
yosys> help nlutmap¶
nlutmap [options] [selection]
This pass uses successive calls to 'abc' to map to an architecture. That provides a small number of differently sized LUTs.
The number of LUTs with 1, 2, 3, ... inputs that are available in the target architecture.
Create an error if not all logic can be mapped
Excess logic that does not fit into the specified LUTs is mapped back to generic logic gates ($_AND_, etc.).
