+# Remarks:
+# - No need for MODELSIM_TCL environment variable and modelsim.tcl, because these are not preferred and instead call commands.do via -do argument.
+# - No need for MODELSIM environment variable to point to a specific modelsim.ini file, because RADIOHDL can use the default modelsim.ini
+# - For RADIOHDL the modelsim project files are created by a Python script.
+# - The paths to the IEEE libraries are defined by the MODELTECH environment variable that gets defined by Modelsim itself when it starts
+# - The paths to the FPGA technology libraries are defined in the [library] section in the modelsim project files using MODEL_TECH_ALTERA_LIB
+# environment variable that gets defined in quartus_version.sh. Similar paths to generic libraries are defined using their absolute path.
+# - Default modelsim.ini settings can be overruled by project specific settings in the [vsim] section in the modelsim project files.
