Messages that result from individual commands appear in the log file as well as in the GUI console if it is active. These messages are generally numbered to identify specific issues and are prefixed in the log file with “INFO”, “WARNING”, “CRITICAL_Warning”, “ERROR” followed by a subsystem identifier and a unique number.

The following example shows an INFO message that appears after reading the timing library.
INFO: [HD-LIB 1] Done reading timing library 
These messages make it easier to search for specific issues in the log file to help to understand the context of operations during command execution.

Generally, when an error occurs in a Tcl command sourced from a Tcl script, further execution of subsequent commands is halted. This is to prevent unrecoverable error conditions. There are Tcl built-ins that allow users to intercept these error conditions, and to choose to continue. Consult any Tcl reference for the catch command for a description of how to handle errors using general Tcl mechanisms.
