## NLUT.RAM

Set to make a RAM* family primitive, otherwise is a SRL or LUT function generator.


## NLUT.SMALL

Seems to be set on smaller primitives.


## NLUT.SRL

Whether to make a shift register LUT (SRL). Set when using SRL16E or SRLC32E


## WA7USED

Set to 1 to propagate CLB's CX input to WA7


## WA8USED

Set to 1 to propagate CLB's BX input to WA8
