TG68 - The Open Source Minimig CPU into the FPGA

[billt]

VHDL? Ewww! Just kidding. This is really cool. Thanks TobiFlex! (Though it would have been even more cool in verilog)

Is there a free vhdl simulator ala Icarus, or a translator, or can Icarus do vhdl since I last read up on it? I can use Modelsim at work but am not supposed to use it for not-work things.

In partial answer to my own question, though I'm not sure if any are good or even workign at all yet:

Though the 68K in VHDL and Minimig in Verilog poses a full-system simulation challenge. Modelsim can do multi-language simulations. Is there a working free simulator that does this?

Sorry if this is a dupe but myprevious comment seems to have disapearred.


The DE1 board looks very cool, but I do have a few concerns.

1) The USB "blaster" port sounds like it's only an uplink to a host computer for programming the FPGA, not for using keyboards/mice/digital cameras/memory sticks/etc. on the DE1 system.

2) Sounds like there's only 1 PS/2 port for EITHER keyboard OR mouse, not both

3) The PS/2 port is off the side instead of along the back with the other connectors.

Maybe all this can be compensated for with something added on one of the IDE looking expansion headers.

And a question, is this thing a standard form-factor such as Mini-ITX to easily fit some case, or is it an oddball format that requires hacking a case? I'm OK with hacking a case, but it'd be awfully convenient if it just fit a standard one.

That's not a problem since you can use a splitter. My laptop just has one PS2 port but I can use simultaneously both keyboard&mouse.

I didn't know PS/2 ports could do that. Cool.
