12 years agoBridges are used to control topology. The pipeline bridge puts pipeline stages in between masters and slaves and the clock crossing bridge allows transactions to change clock domains in an efficient way. This document was written a while back for SOPC Builder designs but the information about the two bridges should be still relevant in Qsys: http://www.altera.com/literature/hb/nios2/edh_ed51007.pdf
The bridges in Qsys *are* different than the ones in SOPC Builder but they perform the same functionality.
