* Gowin. FFs placement.
* Allow clusters to be created from FFs and LUTs;
* Immediately create pass-through LUTs from free LUTs adjacent to FF - at the same time ensure alternating use of LUT inputs;
* In case of constant networks, such pass-through LUTs are disconnected from networks altogether;
* Allow FF to be placed directly into SSRAM slides - this is useful when using synchronous reading.
