Working with a Project
3-42 Projects and system initialization ModelSim Xilinx User’s Manual
3 Project design simulation settings describe how a specific design unit is loaded and
simulated. The simulation settings are edited from the Design > Load New Design
pull down menu or by clicking the Load Design icon.
4 Project simulation settings describe simulation specific behavior. These settings are
edited from the Options > Simulation pull down menu.
Project setting changes take place at different times. General Project editing
(Options > Edit_Project) is disabled while compiling or simulating and project-
wide settings become effected after their change. Compiler option editing
(Options > Compile) is disabled while compiling and takes effect at the next
compile. Project design simulation settings (Design > Load New Design) take
effect at design load/reload. Simulation option edits (Options > Simulation) are
enabled during simulation and take effect immediately.
Using project settings with the command line tools
Generally, projects are used only within the ModelSim graphical user interface.
However, standalone tools will use the project file if they are invoked in the
project’s root directory. If invoked outside the project directory, the MODELSIM
environment variable can be set with the path to the project file
(<Project_Root_Dir>/<Project_Name>.mpf).
The project command
The project command (CR-76) is used to perform common operations on new
projects. The command is to be used outside of a simulation session. See
"ModelSim Commands"
(CR-11) for complete command details.
