DADiSP SPL Debugger Downloads

Download Instructions

• Click the "Download Now" button and OPEN or SAVE the file.
• If the SPL Debugger does not self-extract, run the self-installing executable dbspl20.exe from the Start-Run Taskbar or a MS-DOS command window.
• The SPL Debugger will install in the Modules directory of your current installation. The SPL Debugger requires DADiSP 6.9 B01 or higher.

SPL Debugger 2.0 Features

The debugger provides a simple source level, GUI based interface to debug SPL functions and routines. The debugger supports the following features:

• One click source line stepping.
• Step into and out of SPL functions.
• On the fly expression evaluation and variable assignments.
• One click examination of global and local variables.
• Function and line number based breakpoint definitions.
• Call stack examination and manipulation.
• Color coded syntax highlighting of SPL source files.

Using the SPL Debugger

Once the SPL Debugger has been installed, use the debug or db commands to debug an SPL function. For example, try the following debug session:

db roots roots(1..5)

The SPL Debugger is invoked and a breakpoint is set 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 RESIZUEZ 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.

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.
