Hello
I am just getting into the Lattice Dimanod with MachXo2 stuff. I am also learning Verilog at the same time.
So far, I have managed to make counters and other interesting stuff.
Now, for a real project, I need to load a heap of data into the pld via some sort of bus. I could use the SPI bus peripheral but just to get started, I would like to use a simple parallel memory interface with datalines, address lines and read /write strobes.
I think know how to implelement that but my question is how do I get this asynchrounously incoming data from the external host synchronised with my internal PLD clock so I don't get glitches when the internal circuitry needs that data?
It is probably a real simple standard method but I have unfortunately become a bit rusty on that sort of stuff.
Best regards
