I'm using it to load a constant from a file at compile time.

The goal is to make a prom out of logic gates. It's a silly goal, but I don't make the goals, I just do what I'm told. This - Initializing a ram from file-- problem?? There's more than one way to get your ROM data in besides file operations. It seems to be only upset about the read procedure that returns a char. When I comment that one out, none of the other reads cause an error. I'm not sure why that one in particular is a problem, but perhaps I can discard the leading :'s from the file in some other way Your synthesis tool doesn't have a procedure body for read in it's library.

A shortcoming that prevents you from using it and one you can't overcome. The intention is to prevent file read programmatically.

Xilinx has their own way of loading ROM images, I believe Altera recently implemented something recently, too. Buy a Go Board! The Go Board. FPGA YouTube Channel. Search nandland. Modelsim simulation wave output. Content cannot be re-hosted without author's permission.
