JTAG Chain on FMC
The JTAG chain on the Apollo S10 board supports JTAG interface extension to the
FMC connector so that the JTAG device on the user's FMC daughter card can be
joined with JTAG chain on the Apollo S10 board. Users can enable this feature through
the switch (
SW4.2
) on the Apollo S10 board. In the board's default setting, the JTAG
interface of the FMC connector is bypassed to keep the Apollo S10 board JTAG chain
to maintain close loop. For detailed setting, please refer to Section 2.2:
JTAG Interface
Switch.
Transceiver Channels Speed
There are 10 transceivers connected to the Stratix 10 FPGA on the FMC connector,
two of which belong to the GX channels, and the maximum transmission speed is 17.4
Gbps. The other 8 belong to GXT channels, and the maximum transmission speed can
reach 25Gbps. For details, please to see "
Intel ® Stratix® 10 L- and H-Tile
" for section
“
1.3. L-Tile / H-Tile Building Blocks
”.
lists the distribution and speed of the two channels of the FMC connector.
