    cannot use $cds_analog_exists() or $cgav() Reply
    Hey all,
     
    do I need to use any special option in order to use the cadence system tasks to fetch values associated with analog objects (i.e., $cds_analog_exists() or $cgav() )?  I'm using irun version 11.10-s057.
     
    Here is a trivial example:  
     
    File cgav.v  
    module test;
       wire testv;
       initial
         begin
    #0;
    if ($cds_analog_exists("testv"))
      begin
         $display("testv belongs to the analog domain");
      end
         end   
    endmodule 
     
    Here how I try to run it: 
     > irun  cgav.v  
     
    Here is what I get: 
    *W,MISSYST (./cgav.v,9|22): Unrecognized system task or function (did not match built-in or user-defined names)  
    *E,MSSYSTF (./cgav.v,9|22): User Defined system task or function registered during elaboration and used within the simulation has not been registered during simulation.
     
     
    Thanks much!

    I figured the problem! I need the analog kernel to be able to use these functions.
