Stratix GX Transceiver Merging
A transceiver block contains four transceivers. In a design, an altgxb
instantiation is placed in one or more transceiver blocks and potentially
leaves unused transceivers in a block. For example, a six transceiver
instantiation completely fills one transceiver block and half fills a second,
taking up two full transceiver blocks. If another instantiation is in the
design, it is placed the same way. For example, an instantiation of two
transmitters takes up a third transceiver block. Merging two of the
partially filled transceiver blocks into one transceiver block reduces the
resources used and allows a design to fit into a device with fewer
transceiver blocks.
