Stepping through Lines of Code

You can examine the order in which the simulator executes the statements in your model by stepping through the simulation line by line.

While you can always single-step through the statements in the analog block of a module, outside the analog block, you cannot single-step or set line breakpoints in a particular design unit unless you compiled the unit with the -linedebug option. If you compiled the unit without this option, you can use the run -step or run -next command to run the simulation until the next point where it can stop. If execution passes to a unit that you compiled with -linedebug, full single-stepping resumes.

• If you are using the Tcl command-line interface:

• Use run -step to simulate to the next executable line of code in any scope. This command runs one statement, stepping into subprogram calls.

  The -step option does not step into function calls made by an analog statement. In this situation, the behavior of the -step option is identical to the behavior of the -next option.

• Use run -next to run one statement, stepping over any subprogram calls.

• If you are using SimVision, choose Simulation - Step or Simulation - Next.
