FPGA Reconfiguration
The following description is referring to Figure 8.
Once configured.
When a TISRESET is received by the SMT358, the CPLD and the FPGA are reset.
4) The CPLD owns Comm-Port 3 and can configure the FPGA with a new bitstream
(repeat step 2).
5) The CPLD can leave Comm-Port 3 available to the FPGA and enter an Idle state
on receiving the command BCBCBC00.
Figure 8: FPGA reconfiguration
FPGA Reconfiguration in real time
The SMT358 can be reprogrammed on-the fly by sending a new bitstream to the
Virtex/E FPGA.
It is possible to reconfigure the Virtex/E dynamically by sending a reconfigure
command to it.
The circuit recognizing a reconfiguration request must be implemented in the FPGA,
so any user-defined command can be sent over a Comm-port for instance.
An example design is provided in the software package for the SMT358 (SMT6358).
