DADiSP 6.7 B02 Release Notes

Using the SPL Debugger

The debug or db commands start the SPL debugger and set a breakpoint in the specified function. For example, following debug session:

  db roots

invokes the SPL Debugger and sets a breakpoint in the roots function. The Command Line will display a red prompt background to indicate debug mode.

Since the roots function is called, the debugger will display the source code and pause at the first executable line. Use the GUI interface to step through code, set breakpoints and evaluate expressions. Click on any variable to display its value.

Because a breakpoint has been set in the roots function, the debugger will pause whenever roots is called. For example, invoking the residuez function through the pull down menus:

  Analysis » Signal Processing » Partial Fraction Expansion

causes the debugger to stop in roots because residuez calls roots.

Use the appropriate debugger buttons to step through and into SPL functions, move up and down the stack and show the function call sequence. SPL Debugger

Examining Variables

Use the debugger command prompt to examine global and local variables by entering the variable to examine or simply click on any variable to view its current value in the output display area.

Setting Breakpoints

Press the Breakpoints button or use the db function to set additional break points in SPL routines and to set a break point at a specific line number.

Clicking the left mouse button in the left margin of a line also sets a new breakpoint or clears an existing breakpoint.
