Verification

1. Channel 3 simulation:

• DDR initialization through i2c - done.
• write to DDR - done.
• read from DDR - done.

2. PHASE_SHIFT in DCM is not available currently, because the model had bad constructs, but SDCLK(SDNCLK) can be controlled by "phsel".

For correct writing/reading from DDR in model set phsel="01" (register=0x1008, value=0x00000004).

          ==Board tests==

1. I2c check

a. It doesn't work when assemled with mcontr and 2 DCMs.
b. Started from the beginning. Works.
c. Checked i2c four read with 1 start. Works fine.
d. Adding DCMs.

2. Check BRAM read/write. All's fine

3. Check DDR read/write. Some problems. not solved

4. Three different boards operate identically: BRAM - ok, DDR - not

Understanding how 353's mcontr works

02/28/08: 15:04 for mode=0 ( 8 - burst length)

TileX - number of (32x8) blocks
Seq_par(or Param) - the last write block length - (Seq_par)x8
TileY - number of TileX
All this starts from StartAddress
