say hello to MiST
After having GX Starter Kit with the same board size and HDMI, it's really weird to see a newer board with going back to old VGA output...
Yeah, it's a pitty. I suspect the reason is that Terasic wanted to continue the concept of the old DE-1/2 educational boards with several legacy peripherals that can "easily" be implemented on a FPGA core. But yes, it's a shame. It is possible to add an HDMI board at the high speed connector. But this will increase the cost even more!
it's arguable. FPGA on DE10-nano has industrial grade which give guaranties of more stability on wider temperatures range. So, with tend to heat of FPGA chip this -6 grade against -7I is not a real advantage.
Btw, there is no Altera/Intel documents saying what exactly this number means besides that 6 is less than 7. It's not like SDRAM chip where -6 and -7 means particular delay in datasheet. In FPGA it's more hypothetical than real difference.
The advantadge of the industrial grade is only relevant if the board and the device heats outside of the normal temperature range. But the DE-10 Standard doesn't have, not nearly, the heating issues that we see on the DE10-nano. And this is likely the reason that Terasic used the industrial grade on the nano in the first place.
The difference in speed grade is not hypothetical at all. The datasheet doesn't cover all the timing parameters because that would be impossible, they are too many. Contrary to other chips that might have just a handful or a dozen timing parameters, a FPGA might have hundreds.
But there are performance spreadsheets available. And you can see the actual performance using timing analysis. Compile just about any core, once with one speed grande and another time with a different speed grade, and you will see a considerable difference in the result.
I'm pretty sure that ao486 can run faster on the DE10-Standard.
Generally speaking DE10-standard is not a bad board and it's more convenient for debugging.
The stopper here is the price. With $350 it's better to make a custom board which will include all required components.
I think we all agree with that. But the "MiSTer" port to the DE-10 standard doesn't harm. As somebody just said, at least not as long as most of the work is done by somebody else.
