HI guys,
Recently i adquired a Terassic DE1 Board.
The minimig version 12e, already syntetized, runs very stable in the
board.
I syntetized successfully the version 12e, my self, but is not very
stable, hangs so often when the Amiga is accesing intessively to the
SDRAM.
I'm using Quartus II V7.2 SP3.
The only one error i get is in the timing analysis and is the following:
Clock Setup: 'amigaclk:inst8|altpll:altpll_component|_clk0'
slag -22.998 ns
required: 114.76 MHz ( period = 8.714 ns )
actual: 31.53 MHz ( period = 31.712 ns )
You get this error when do the syntesis?
The minimig version 13 doesnt run in my board, i tried several times
with different SD cards, but i was not able to load the kickstart, it
hangs after loading the spihost.
The difference i found in my Terasic DE1 pcb is that it uses a SDRAM
from PSC, A2V64S40CTP - G7 (G7 is 133MHZ SDRAM COMPATIBLE) instead of
the ISSI part found in the schematic.
Anybody has problems with version 13?
Best Regards
