Hi! I am trying to follow your tutorial on the 1-bit fulladder using alliance installed on windows NT. I have gone through the asimut already without having any errors. However when I tried to execute genpat, it generated the following message: Generating the Makefile Compiling, ... Current execution environment MBK_CATA_LIB : . :/usr/local/alliance/archi/Cygwin/cells/sxlib:/usr/local/alliance/archi/Cygw in/cells/padlib MBK_WORK_LIB : . MBK_IN_LO : vst MBK_OUT_LO : vst MBK_IN_PH : ap MBK_OUT_PH : ap MBK_CATAL_NAME : CATAL Executing ... Removing tmp files ... rm: halfadder : no such file or directory <-- is this ok? Hoping for your immediate response. Thanks a lot! =) *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~* MARLA A. CUYUGAN Science Research Specialist II Advanced Science and Technology Institute
