executing ncsim commands from verilog using system task

Arturi

Hi all,

I would like to be able to execute ncsim tcl commands from my verilog code.So intead of sourcing a tcl file at the beggining of the simulation, I would like my design to react on events and source the tcl script on its own.

 something like:

@(posedge event_signal)

$source_tcl_script("./my_ncsim_commands.tcl");

 

I was wondering if cadence has implemeted a system task for that.  Or how could I implement such.

 

Cheers

    The Verilog source code doesn't know anything about the TCL interface that is controlling it. But the TCL does know about the Verilog. So the place to do this is in the TCL.

     

    You can create a TCL breakpoint using the "stop" command that will watch for a signal and execute a command as a result. Before the simulation starts, execute a command like:

     

    stop -condition {#event_signal == 1} -execute { input ./my_tcl_commands.tcl }
