Source Display

Main GoLogic Help

Description
The Source Display PlugIn maps the address bus values to line numbers in the original source code. The source code can use any language such as C, C++, Pascal, Fortran, Ada, etc.

The Source Display PlugIn uses a symbol table’s debugging information to determine the address values for each source code line. The line-number information in this file is created by the compiler or assembler used on the source code. The Source Display PlugIn cannot operate without this line-number information.

Load a symbol table into the channel group associated with the address bus. An error message is displayed if a valid symbol table is not loaded into the address bus. Symbol tables are loaded into the channel groups in the Setup window's Channel group's tab. See the Chapter 3 - Setup step two: channel groups chapter for details on how to load a symbol table into a channel group.
