* Maximum delay calc (Ch 1):
|

* clock prop + dram skew + max dqs prop delay + clk_adjust + min chip dly
|
||||
* 1.46" * 180+ 350ps + 1.1" * 180 + 1563ps + 2595ps
|
||||
* = 4968ps
|
||||
* = 4.968ns
|
||||
*
|
||||
* Ch.0: 3.341ns to 5.673ns additional delay needed (pick 4.5ns as target)
|
||||
* This is 1.8 clock cycles, pick CPO = READ_LAT + 7/4 (0x9)
|
||||
* Ch.1: 2.822ns to 4.968ns additional delay needed (pick 3.9ns as target)
|
||||
* This is 1.56 clock cycles, pick CPO = READ_LAT + 3/2 (0x8)
|
||||
*
|
||||
* Write latency (WR_DATA_DELAY) is calculated by doing the following:
|
||||
*
|
||||
* The DDR SDRAM specification requires DQS be received no sooner than
|
||||
* 75% of an SDRAM clock period—and no later than 125% of a clock
|
||||
* period—from the capturing clock edge of the command/address at the
|
||||
* SDRAM.
|
||||
*
|
||||
* Based on the above tracelengths, the following are calculated:
|
||||
* Ch. 0 8572 to DRAM propagation (DQ lanes) : 1.9" * 180 = 0.342ns
|
||||
* Ch. 0 8572 to DRAM propagation (CLKs) : 2.3" * 180 = 0.414ns
|
||||
* Ch. 1 8572 to DRAM propagation (DQ lanes) : 0.7" * 180 = 0.126ns
|
||||
* Ch. 1 8572 to DRAM propagation (CLKs ) : 1.47" * 180 = 0.264ns
|
||||
*
|
||||
* Difference in arrival time CLK vs. DQS:
|
||||
* Ch. 0 0.072ns
|
||||
* Ch. 1 0.138ns
|
||||
*
|
||||
* Both of these values are much less than 25% of the clock
|
||||
* period at DDR2-600 or DDR2-800, so no additional delay is needed over
|
||||
* the 1/2 cycle which normally aligns the first DQS transition
|
||||
* exactly WL (CAS latency minus one cycle) after the CAS strobe.
|
||||
* See Figure 9-53 in MPC8572E manual: "1/2 delay" in Freescale's
|
||||
* terminology corresponds to exactly one clock period delay after
|
||||
* the CAS strobe. (due to the fact that the "delay" is referenced
|
||||
* from the *falling* edge of the CLK, just after the rising edge
|
||||
* which the CAS strobe is latched on.
