How to add device library to modelsim

Refer to Altera's "modelsim tcl scripting examples (https://www.altera.com/support/support-resources/design-examples/design-software/tcl/tcl-modelsim.html)" for details on using the Altera libraries for simulation.

The example doesn't specifically include Cyclone IV - it's a little (very) out of date. However, a new Quartus installation will include all the files you need. Modify/use the bits of the script as necessary.

Cheers,
