Honored ContributorRead binary file to binary vector array
If I have a binary txt file is there a way in Quartus to read the file and store it as, say, an array of binary vectors? Thanks.

Honored Contributor --- Quote Start --- Ah yes I failed to mention that I will be writing this binary data to the SDRAM on my DE2-115, and will therefore need to synthesize it. So how should I use file I/O to initialize a signal with the binary data? --- Quote End --- You cannot initialize external memory from the .sof image. You could however store the SDRAM contents in the external configuration device (EPCS, flash, whatever) and have your logic copy data from the configuration device to SDRAM after configuration. Personally, I would just use your development machine to write the contents to SDRAM, see this tutorial: http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial Cheers, Dave
