MulSpliter

object MulSpliter

MulSpliter is a tool which will cut a multiplication into multiple smaller multiplications Those smaller multiplication results would need to be summed together. MulSpliter Doesn't generate any hardware by itself, but instead provide you with the datamodel of the work to do. Usefull for large multiplications which need to be pipelined on multiple cycles when retiming isn't good
