Question on Schematic to VHDL conversion.

I'm new to programable logic, most of my experience has been with microcontrollers. I know a little about VHDL but not enough right now to program with it. I do know schematics and so I designed my...

I wouldnt rely on or use the Schematic -> HDL converter if I could avoid it. Its not that great, and Ive come across bugs with it, mainly with 2D arrays in schematics being converted to 2d std_logic_vectors (that dont exist as a type). The only time Ive used this feature is when I need to run a simulation on a schematic in modelsim. Then you have the problem of the crappy signal naming for unnamed connections (as you've found).

I would say learn digital design from the schematic, and then try and write your own version of the schematics file. I dont think the auto-generated VHDL is going to teach you alot.
