Sure, I do it all the time. I use QuartusII v13.0sp1 which is the LAST/LATEST version that supports the CycloneII series.
Still downloadable via the Intel/Altera Quartus download portal.
Sorry, I don't use modelsim for my simulations. I've always used another 3rd party verilog simulator.
IIRC when you download 13.0sp1 there is a separate file you need to download for the companion modelsim simulator.
I don't believe modelsim (which is not an altera product) is bundled in the quartus download.
I went to the Intel/Quartus download page for FPGA tools, and 13.0sp1 does not seem to be available for download anymore.
The earliest free/web version I could select of the Quartus tools was 17.0 (which does not support CycloneII).
The 14.0 version of the subscription version was available for download, but that requires a paid license.
So as best as I can tell 13.0sp1 is no longer available, so Cyclone/CycloneII support, and MAX3K/MAX7K CPLD support, are defunct.
Glad I downloaded the complete set of files several years ago.
Intel stop being so **bleep** and please leave your old tools up for download for us old guys supporting old devices.
I was hoping that Quartus Prime would support Cyclone II and provide a simulation tool but this looks like a dead end too. It's too bad because there are a lot of Cyclone II applications still in use that need support. Fortunately us "old guys" can still swing a o'scope. Theres more than one way to debug a design.
Thanks All for your Help!
QuartusII Web (Lite) is back up on the download page as of this posting time (2022-01-09 10:00am PST).
Get it while it is still available... also includes ModelSim download file.
