The second node (node1) is shown in Figure 38.

It receives two sequences of data, from Diamond channel 0 (read) and Diamond channel 1
(read), respectively, which receive data from node root, as shown in the top diagram. These
are summed up together and the result is:
• Printed (sim_printf) to the console;
• Sent to the Diamond channel 0 (write), which is connected to the node root, as shown in
the top diagram;
• Muxed into a 2-elements vector and sent, via Diamond channel 1 (write) to the FPGA
module, as shown in the top diagram.
The sim_digHwInterface is exactly as in node root, as this is the second DSP of the same
SMT362 board.
The third node SMT350 implements the Simulink diagram that programs the FPGA +
ADC/DAC combination (in this example, SMT351T + SMT350 board). The SMT350
diagram is shown in Figure 39. This demonstrates how the SMT6040 can be used to program
FPGA modules and also to configure the SMT350 DAQ board.
