GENERAL (NON-SCSI) ROUTING RULES:
--> USE 5 MIL TRACES FOR 60 OHM SIGNALS ON ALL ROUTING LAYERS
--> TRY TO USE ISLANDS FOR ALL POWER SIGNALS WITH NO POWER PLANE.
IF ISLANDS ARE NOT POSSIBLE, USE AT LEAST 25 MIL TRACES.
EG. GND, 3.3V, A_TRMPWR, B_TRMPWR
--> IF POWER SIGNALS DO HAVE A PLANE, USE AT LEAST 25 MIL TRACES WHERE NEEDED
--> USE MINIMUM 10 MIL TRACES FOR THESE SIGNALS:
LEDACT*, LEDFALT*, LEDONLN*
--> USE MINIMUM 20 MIL TRACES FOR THESE SIGNALS:
GATE12V_* & GATE5V_*
--> USE MINIMUM 25 MIL TRACES FOR THESE SIGNALS:
12VBAY_*, 5VCHARGE_*, 5VBAY_*
--> I2C SIGNALS SHOULD BE ROUTED SERIALLY. THERE SHOULD NOT BE ANY LONG
--> I2C1_D & I2C1_CLK SHOULD BE ROUTED TOGETHER
4
TRY TO KEEP THESE SIGNALS AWAY FROM OTHER SIGNALS.STUBS OR BRANCHES.
SCSI Bus = 250 mils
Differential Pair = 50 mils
Stub Lengths (Bus) = 500 mils
Stub Lengths (Pair) = 100 mils
NOTE ON SCSI ROUTING RULES:
--> SCSI SIGNALS ARE NAMED A(B)_*. THERE ARE 27 DIFFERENTIAL PAIRS
--> AVOID VIAS WHENEVER POSSIBLE.
--> IF VIAS ARE USED, USE THE SAME NUMBER OF VIAS BETWEEN ± DIFFERENTIAL
SIGNAL PAIRS.
--> TRY TO ROUTE ALL THE ± DIFFERENTIAL SIGNALS ON ONE LAYER
IF POSSIBLE, ROUTE THE SCSI BUS ON TWO ADJACENT LAYERS (INNER 1 & 2).
--> IF INNER 1 AND INNER 2 BOTH HAVE PARALLEL TRACES THERE MUST BE A MINIMUM
DISTANCE OF 15 MILS BETWEEN THE PARALLEL TRACES ON INNER 1 & INNER 2.
THEY CANNOT BE OVER EACH OTHER.
--> ROUTE EACH ± DIFFERENTIAL PAIR PARALLEL
--> BUS SPACING TO ANY OTHER SIGNAL SHOULD BE AT LEAST 2X, WHERE X IS THE
EDGE-EDGE SPACING OF THE DIFFERENTIAL PAIR
--> USE ARCS OR 45 DEGREE BEVELS AND AVOID 90 DEGREE BENDS
--> TRY TO ROUTE ALL OF THE LVD SIGNALS ON THE INNER LAYER CLOSEST TO THE
GROUND PLANE
--> STUB LENGTHS TO BE LIMITED TO 3 INCHES
