Description
The add_bp command lets you add breakpoints to an HDL source file to pause the current simulation.
A breakpoint is a user-determined stopping point in the source code used for debugging the design. When simulating a design with breakpoints, simulation of the design stops at each breakpoint to let you examine values and verify the design behavior.
You can report breakpoints in the current simulation using the report_bps command, and remove existing breakpoints using the remove_bps command.
The add_bp command returns an error if the command fails.
Arguments
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<file_name> - (Required) The name of the HDL source file to add a breakpoint to.
<line_number> - (Required) The line number of the specified <file_name> to add the breakpoint to.
Examples
The following example adds a the breakpoint to the HDL source file at the specified line number:
add_bp C:/Data/ug937/sources/sinegen.vhd 137
