NIRGAM error after initial installation

[Vin]

Dear All,

 

   I am PhD student at  UNSW, Australia. Recently, I downloaded version 2.1 and tested the simulator. I get the following error without making any changes to any file in the source code or config files.

 

Error: (E115) sc_signal<T> cannot have more than one driver: signal `noc.nwtile[1][2].signal_26' (sc_signal)
   first driver `noc.nwtile[1][2].IC2.port_21' (sc_out)
   second driver `noc.nwtile[1][2].IC1.port_21' (sc_out)
   In file: ../../../../src/sysc/communication/sc_signal.cpp:137

 

I tried writing "export SC_SIGNAL_WRITE_CHECK=DISABLE" in .bashrc, still I get the error.

 

I am new to NIRGAM. Please help.

[Vin]

Dear All,

 

   It works when I execute "export SC_SIGNAL_WRITE_CHECK=DISABLE"  in the directory.

 

  

With Thanks

Vinitha

Dear Manoj Bohra,

 

    The simulator is installed in a linux server. The simulator works now after executing export command in the directory.

Hi Manoj,

Thanks for looking into this. I am able to install nirgam, the error was with systemC.

I guess I was working with older version of SystemC. Now I am trying to run few examples.

I will update you if I found any issues further.

Thanks,
Anuradha

[Manoj Bohra]

Dear Anuradha

[jayesh dalal]

u can firstly installed ubuntu 10.10 version ....because nirgam simulator is working on that version smoothly.
