Dear all, This is regarding XTK simulation. The stack details added in the GCF file is given below which is generated by axxxx -stack_gen <gcf file> # ------------------------------------------------------------------------ # GCF STACK Section # Generated by AXXX version Version 2.1.9 on Sat Sep 20 16:34:19 2003 # ------------------------------------------------------------------------ STACK LAYER (0) = SIGNAL ( NAME = TOP, THICKNESS = 2.000000, DIELECTRIC = 1.000000 ) INSULATOR ( THICKNESS = 7.900000, DIELECTRIC = 4.500000 ) LAYER (1) = SIGNAL ( NAME = 3V3, THICKNESS = 1.400000, DIELECTRIC = 4.500000 ) INSULATOR ( THICKNESS = 6.000000, DIELECTRIC = 4.500000 ) LAYER (2) = PLANE ( NAME = GND, THICKNESS = 1.400000, DIELECTRIC = 4.500000 ) INSULATOR ( THICKNESS = 7.900000, DIELECTRIC = 4.500000 ) LAYER (3) = SIGNAL ( NAME = BOTTOM, THICKNESS = 2.000000, DIELECTRIC = 1.000000 ) END_STACK When I execute axxx <gcf file > ie with the gcf file containing the above stack details, axxxx.log file gives the following message in it. Layer Stackup (Information only): Layer count = 4 Default Connection Map = 1101 LAYER (0) = SIGNAL ( NAME = "TOP" ) INSULATOR = ( ) LAYER (1) = SIGNAL ( NAME = "3V3" ) INSULATOR = ( ) LAYER (2) = PLANE ( NAME = "GND" ) INSULATOR = ( ) LAYER (3) = SIGNAL ( NAME = "BOTTOM" ) Is this response OK? Or any of the parameters in GCF will be reflected in the log? Pleas help Thanks in advance Ranju ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
