Hey community,
I want to cascade DSP48 slices. But what happens with the regular P output when I cascade with the PCOUT. Just put it on a signal and never use it?
Furthermore, is there a possibility to set the size of PCIN and PCOUT? The wizard choose every time the maximum size of 48 bits which I would like to avoid.
Thanks

If you don't need it, just ignore it.

No, PCOUT is routed directly to the next PCIN, there's no way to manipulate or read it.
