Cyclone II - Cyclone II Is it possible to develop Cyclone II devices on Quartus Prime? Replies: Re: Cyclone II Whoa! Thanks for the heads up! I got it all. Now we see how the install goes. Thanks So Much! Replies: Re: Cyclone II QuartusII Web (Lite) is back up on the download page as of this posting time (2022-01-09 10:00am PST). https://fpgasoftware.intel.com/13.0sp1/?edition=web&platform=windows Get it while it is still available... also includes ModelSim download file. Replies: Re: Cyclone II 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! Replies: Re: Cyclone II 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. Replies: Re: Cyclone II 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. Replies: Re: Cyclone II Thanks for your reply. Yes, I am using Quartus II 13.0.sp1 which does support Cyclone II. I have even produced a design. However, when I try to run RTL I get a message that the modelsim-altera eda executable is not located. I know how to set the path under Tools->Options but I can't find the executables. From other posts I understand I should look for " C:\altera\13.1\modelsim_ase\ win32aloem\ " (or similar)) but this path does not exist in my version. Do you know where I can get these executables? Replies: Re: Cyclone II 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.
