Abstract
Methods and apparatuses to automatically synthesize circuits. In one aspect of an embodiment, a logic function feeding a carry chain is implemented through extending the carry chain and through using the extended portion of the carry chain. In one aspect of an embodiment, control/non-control loads are separated from each other through replicating the driver elements of the mixed control/non-control loads. In one aspect of an embodiment, a read only memory (ROM) is implemented using a random access memory (RAM). In one embodiment, a register at the input side of the ROM is generated through inserting a register that is clocked at an inverted clock signal or through retiming a register from the output side of the ROM.
