In File modelsim.py method _create_modelsim_ini
Many problems arise when libraries already exist or when certain files—usually protected—need to be precompiled. This can be solved with env. VUNIT_MODELSIM_INI, but not if modelsim.ini changes after vunit compile or even during it. The initial modelsim.ini must first be adjusted again because vunit creates a new modelsim each time. This is a hindrance for very complex designs.
Therefore, the suggestion is NOT to overwrite modelsim.ini if it already exists.
Questasim change the option for modelsim.ini from -modelsimini to -ini.
So add a member ini_flag and change all -modelsimini to f"{self.ini_flag} and add a version check if vsim < 2025 for modelsimini
