stub length
1) The trace lengths should be controlled to 1.8" min. and 4.3" max. from socket370 to BX Chipset
2) The stub lengths should be controlled to 0.0" min. to 2.0" max from socket 370 to R packs.
3) The AGTL+ bus trace width is 5 mil. not greater than 6 mils.
4) The edge to edge trace spacing is 12 mils. The ratio of this spacing to the delectric thichness of the
layer should be at least 2.
5) The minimum spacing can be decreased to 5 mils for escaping the FCPGA/PPGA areas for a length of
less than 0.25"
6) The AGTL+ signals should be routed on the signal layer next to the ground layer (referenced to ground).
7) ***** TEST SIGNALS **** Route 3 AGTL+ signals at the minimum of 1.8" for testing purposes. The 3
signals must be on the BX side. Use these three signals: BNR#, HD4# HA27#.
8) ***** TEST SIGNALS **** Route 5 signals next to each other at the maximum of 4.3". This is to test
crosstalk. The five signals are: HD29#, HD28#, HD43#, HD37#, HD44#.
