MULTSIGNOUT is a software abstraction of the hardware signal. It is modeled as the MSB of the multiplier output and used only in MACC extension applications to build a 116-bit MACC.

The MSB of the multiplier output is cascaded to the next DSP58 using the MULTSIGNIN signal and can be used only in MACC extension applications to build a 116-bit accumulator.
