Hint: If you use only vmap without parameters you will get a list of currently mapped libraries, which ModelSim.ini you are currently using and physical location. The ModelSim command window responds to cd and mkdir commands, or you may use the File->Change Directory menu item to navigate to a directory of your choice. vmap writes an initialization file called modelsim.ini into your working directory which contains information about your working environment (like which libraries you are using etc.). Modelsim will compile your design to (GUI: menu File New. So, start by creating a new directory somewhere else on your computer and change your working directory there. Type the following command to create a ModelSim working directory called work. As this directory is my installation path, this is certainly not a directory where I would want to work with my simulation projects. The example above shows my default working directory after I start ModelSim Altera Edition for the first time. To view the path of your current working directory, type the pwd command in the ModelSim command window: ModelSim> pwd When you work with ModelSim, it always has the context of a current working directory. This will be our default view for a later tutorial on Advanced VHDL Simulation. Required default libraries for advanced VHDL simulation When you start up ModelSim Altera Starter Edition, you are greeted with the Library view, showing all the pre-compiled libraries as delivered with the simulator:įig 3.
MODELSIM WORK FREE
It has mixed-language support, supports VHDL-2008, and with their free edition you may run any number of instances. variable (and running vlib from cmd does work), but at the top of all.

This is a follow-up to my article “Advanced VHDL verification on a budget”.
