problem on simulating the Rflib components

ROHIT DWIVEDI

I am using a balun for Diffrential Lna simulation but the simulator produce error due to balun so plz help me how to fix it.

Error found by spectre during AHDL read-in.

    

ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. Check the log file input.ahdlSimDB//4234_artist_rfLib_balun_veriloga_veriloga.va.balun.ahdlcmi/Linux/../ahdlcmi.out for details. If the compiler ran out of memory, use 'setenv CDS_CMI_COMPLEVEL 0', and try again. If the reason for the failure was a syntax error, contact your Cadence Customer Support representative with the netlist, log files, behavioral model files, and any other information that can help identify the problem.

    ERROR (SFE-91): Error when elaborating the instance balun. Simulation should be terminated.

    Did you look in that file? My guess is that you're trying to run on a 32-bit operating system, and that is not supported (since MMSIM11.1 and also most other releases of a similar vintage, we only support running on 64-bit operating systems, even if the software may be running in 32-bit mode). What does the UNIX command "uname -a" report?

    Regards,

    Andrew.

  • I am using Linux RED HAT 5, I am not so good in Linux I am using linux only for CADENCE in my college lab so I anm not able to find the path of the file input.ahdlsimDB file and about operating system I will see and tell you. From where I can see UNIX command report?

    thank you for helping me 

  • Presumably you ran virtuoso in a terminal window (where you typed "virtuoso"), so you could type "uname -a" there. Alternatively, in the CIW type:

    sh("xterm &")

    and in the window that pops up, type "uname -a".

    For the input.ahdlsimDB file, this will be in the same directory as the netlist. If you do Simulation->Netlist->Display and at the top of the window it should give you the path to the netlist directory. You could "cd" in a terminal window to the same place - but to be honest, it doesn't make much sense to try to teach you to use Linux here - we may be a while...

    Regards,

    Andrew.

  • yes sir the linux is of 32 bit. so what to do now? is there need to upgrade it to 64 bit? or is there any other alternative?

  • The right solution is to upgrade your operating system to 64 bit (this is of course assuming that you're running on 64 bit hardware, but if it isn't, it must be very old indeed).

    You might be able to get away with adding "-ac 0 -bc 0" into the userCmdLineOption field in the ADE Setup->Environment window, but certain parts of the tools require the compilation of VerilogA to C (and it's a good idea for performance anyway). So I would focus on getting your machine(s) upgraded.

    Regards,

    Andrew.

  • Ok finally I am going to upgrade the os. But I have few questions 

    can I install 64 bit os on 32 processor?

    is there necessery to install server edition only to run the cadence?

    is there any free resource to download the red hat linux 64 bit?

     if other system of my lab are of older version and i am installing the new version is there any problem with that?

    My questions may be silly but plz help me. 

    thanks fpr your help 

  • You can't install a 64 bit OS on a 32 bit processor.

    Workstation or server editions are both fine.

    The enterprise editions are not free. There are similar (supposedly compatible) distributions such as CentOS but these are not supported - ie we do not test on them.

    It doesn't matter if you have a mix of OS versions on the same network.

    Regards,

    Andrew
