TCL scripting doesn't catch errors, when simulator returns with error (e.g. GHDL)

[Paebbels]

When GHDL returns with a non-zero return code (e.g. for a syntax error), the TCL scripting doesn't catch this error in a clean way and dies.

ghdl: compilation error
child process exited abnormally
    while executing
"exec        $ghdl -a --std=${VhdlShortVersion} -fsynopsys -Wno-hide --work=${LibraryName} --workdir=${GHDL_WORKING_LIBRARY_PATH} {*}${VHDL_RESOURCE_LI..."
    (procedure "vendor_analyze_vhdl" line 19)
    invoked from within
"vendor_analyze_vhdl ${VHDL_WORKING_LIBRARY} ${NormFileName} ${OptionalCommands}"
    (procedure "analyze" line 15)
    invoked from within
"analyze ramp.vhd"
    (file "../src/ramp.pro" line 14)
    invoked from within
"source ${NormName} "
    (procedure "include" line 34)
    invoked from within
"include ${Path_Or_File}"
    (procedure "build" line 50)
    invoked from within
"build ../src/ramp.pro"
    (file "run.tcl" line 6)

Expected behavior:

• catch child process terminations with non-zero exit code
• report an internal simulator error
• note caught error in HTML reporting.
• exit analysis in a clean way without TCL call stack
• maybe report last analyzed file

Related to #21.

I think this is partially addressed, right?

Fixed. Certainly on Dev. Probably on main. In 2022.09, it will be on main.
