fpga

Hi,

I am new to NI.

I need to make a system with embeded controls I am considering using FPGA.

I need to know, if the application program is stored in non volatile memory, as otherwise after a power failure, the application

software would have to be downloaded again? Is this the case in FPGA?

Thanks

On the FPGA I am using (a 7811R) the program is stored in non-volatile memory and should work fine after a restart.

FPGA isn't exactly a program.  It is manipulating gates to perform a specific task.  The definition of the gates does not change with a power outage.

Also, you should compile your code into a bit file. The bit file is then used to program the FPGA.  The process of downloading the bit file is really fast, so I doubt it is something to really worry about (depending on your application).
