Preliminary
TIMING SPECIFICATIONS
Timing design within the module makes demands upon signal timing at the module connectors. This section
describes internal module timing when it is useful to explain external requirements. For detailed information
on timing and latencies see Sun publications:
“UltraSPARC–IIi Highly Integrated RISC Processor, PCI Interface.” Data Sheet, SME1430LGA [1]
“UltraSPARC–IIi User’s Manual,” SME1040CGA [2]
PCI
PCI_CLK and PCI_REF_CLK traces on the module are matched in length to within 0.5 in trace length, or
100 ps at a nominal length corresponding to 550 ps. These signals have no added delay and their trace lengths
are also within
± 0.5 in of those of the other PCI signals. Setup, hold and propagation times are listed in the
Figure 4. PCI Clock Trace Delays
DRAM
DRAM signals are all matched to within 0.5 in trace length on the module.
UPA
Within the module design, the following sets of clock signals need to have minimum, ideally zero, skew
between them.
