Hello sir, I am studying the use of Datapath entities and I read the dlxm tutorial. I am trying to design an adder circuit. I have some questions: 1. How can I rectify the following error and set it properly. " FpGen Macro-Functions library: - FPGEN_LIB : not set" I mean what instruction can I use to set the FPGEN_LIB. 2. Pls kindly help me verify the following settings too: $ export MBK_IN_LO=vst $ export MBK_OUT_LO=vst $ export MBK_IN_PH=ap $ export MBK_OUT_PH=ap $ export MBK_WORK_LIB=. $ export MBK_FPGEN_LIB=/mclib Is the last line( MBK_FPGEN_LIB=/mclib) correct. I saw the setting in dlxm.pdf..sec 3.2.4 and is this the instruction supposed to set FPGEN_LIB? Besides, I didnt find any mclib directory or file in my computer. 3. Heres my output for the command fpgen -v accum o Current Alliance environment: - ALLIANCE_TOP : /usr/local/alliance/archi/Cygwin - ALLIANCE_OS : Cygwin o Current MBK environment: - MBK_IN_LO : vst - MBK_OUT_LO : vst - MBK_IN_PH : ap - MBK_OUT_PH : ap - MBK_WORK_LIB : . - MBK_CATA_LIB : /usr/local/alliance/archi/Cygwin/cells/scr/ /usr/local/alliance/archi/Cygwin/cells/rsa /usr/local/alliance/archi/Cygwin/cells/rfg /usr/local/alliance/archi/Cygwin/cells/dplib /usr/local/alliance/archi/Cygwin/cells/fplib /usr/local/alliance/archi/Cygwin/cells/ring - MBK_CATAL_NAME : CATAL - MBK_VDD : vdd - MBK_VSS : vss - RDS_TECHNO_NAME : /usr/local/alliance/archi/Cygwin/etc/cmos_11.rds o FpGen Macro-Functions library: - FPGEN_LIB : not set o Program generation. - Creating Makefile. - Running Makefile. o Execute program... Interface - Exit code := 0. o Remove temporary file. Is this kind of output correct sir, and about the interface... Exit code:=0, is that correct? What exit code number will tell me that my results are wrong? Thanks GIIE --------------------------------- Do You Yahoo!? Send FREE video emails in Yahoo! Mail.
