# # CMX-0 Nets File # # System-Ace Power and Ground Nets # ----------------------------------- # # # Original Rev. 22-Aug-2012 # Most Recent Rev. 9-May-2012 # # # # This file holds the nets for all of the Power and Ground # connections to the System-Ace chip. This file includes # the power supply bypass capacitors for the System-Ace. # # Recall that the System-Ace will be setup for the 3.3 V # JTAG "Test Interface" connection to the front panel. # This JTAG loop also runs through the JTAG connection to # the TTCDec mezzanine card. This is TSTJTAG. # # Recall also that the Configuration JTAG chain that runs # from the System-Ace to the Board_Support, Base_Function, # and Topological Processor FPGAs is a 2.5 V JTAG string. # This loop is called the CFGJTG. # # Basically: # # 3.3V Vcch supplies the Test JTAG and the Compact Flash ports. # 2.5V Vccl supplies the Configuration JTAG and MPU ports and the core. # # # U321 System-Ace # # C322, C324, C326 47 nFd Bypass capacitors # C321, C323, C325 100 nFd Bypass capacitors # # C328, C330, C332 47 nFd Bypass capacitors # C327, C329, C331 100 nFd Bypass capacitors # # # There are 6 bypass capacitors on the 3.3V supply (3x 47 nFd # and 3x 100 nFd).
