IUS 8.2 internal error

Chintanm

Hello Cadence guys,

When I try to use a variable of type real to give delay as #c ( where c is declared as real), then tool gives me internal error.

but when I use direct number for delay as #10.522  then tool is not giving any error.

Is there any solution for this?

Please reply ASAP.

  • Hi Mickey,

    Thanks for the response.

    I am using IUS 8.20-b003 .

    I am also not able to regenerate the error in a demo code.

    What I am doing is :

    I am generating clock from one class which directly access's the signal of interface. and to generate that clock i have used variable of type real for delay.

    my code line looks like this:

    task clock ();

    real a;

    a =10.625;

    while (1) begin

    #a xyz_interface.clock = ~xyz_interface.clock; ( f I replace a with 10.625 then code works fine)

    end

    endtask

    The whole code is made with OVM 2.0

    Hope this information hepls to find some answer , meanwhile I am trying to make demo code with same error so you can have a look.

    PS : I tried with variable of type int instead of type real and code worked. But I need to use variable of type real. Seems to have some problem with type real. any solution?
