Getting the SDRAM to work

jason | 11 December, 2010 08:50

I had a thought about this while at work yesterday. Everything in the SDRAM code uses positive edge clocks - except for the data reading. With luck, that would be the only thing that needed changing...

This morning, I had a go at changing it - and it worked!

I think that the negative edge clock worked for the slower chip, but after ISE had moved the blocks around, then it stopped working for the faster one.

I have to admit that I was very relieved by this - I didn't want to have to replace the SDRAM with a slower chip, or learn how to fix the positions of various logic elements on the board.
