Honored ContributorVHDL FILE_OPEN does not return correct status in Quartus
I have a procedure in VHDL that reads a line from file and is supposed to assign signal values based on individual characters of the line. The problem i am facing is that my FILE_OPEN statement seems...

Honored ContributorThe problem here is that Quartus does not support memory initialisation from a text file in VHDL. I raised an enhancement request for this about 8 years ago, because Xilinx XST always has allowed the use of textio to initialise a ram. Annoyingly, Quartus does support this in verilog.
Just a NOTE: if it did support it - then you are doing it in the wrong way anway - it needs to be done via a function at initialisation time, not runtime in a process. If the initialisation is easily done via a function, then Quartus does support initialisation via a function (unless it involves textio) Otherwise your only option is to create a .mif file.
