Multi-FPGA high capacity platform through HSMC
The DE4 offers a choice of two Stratix IV GX devices, EP4SGX230 and EPSGX530 which offer
logic elements (LEs) up to 228,000 and 531,200, respectively to provide the flexibility for users to
select a suitable device in terms of design capacity. In situations where users’ design exceeds the
capacity of the FPGA, the HSMC interface can be used to connect to other FPGA system boards
creating a multi-FPGA scalable system.
Figure 2–17
illustrates a connection setup between two
DE4 boards by connecting through port B and Port A of the HSMC connectors using a Samtec
high-speed cable. Notice the JTAG switch (SW8) configuration setup where position 2 is set to
‘Off’ for port B connected on the DE4 and position 1 is set to ‘Off’ for port A connected on the DE4,
allowing JTAG chain to be detected for both DE4 boards.
