Debugging with nSIM

1. Creating C project


_C Project for nSIM debugging_

2. Choosing nSIM gdbserver under Debug Configuration

   

   Choosing nSIM on debug tab

   In this tab, user need to indicate correct properties file/TCF file for current CPU core. In general it is recommended to use TCF files, because they are generated from the Build Configuration Registers and thus most reliably describe target core. nSIM Properties files contain list of key-values for nSIM properties which allow to describe target core and additional simulation features, full list of properties is documented in the nSIM User Guide. It is possible to specify both TCF and properties file, with properties file being able to override parameters set in TCF. For example, if you have a TCF for a little endian core, but would like to simulate it as a big endian, it is possible to create an properties file that will set only a single property for big endian, then in IDE GUI in nSIM GDBserver settings specify bath to both TCF and properties file and that will give a desired results.

   

   To see output from the target application, go to Common tab and check "Allocate console (necessary for input)".
