ContributorEdit IP Catalog IP and saving to different name
Is there a way to edit an existing IP Catalog IP item, change it, and then save it off as a different named IP item? I am using Quartus Lite 20.1.1.
Thanks,
Bill

ContributorFor example, I have a fifo that is 48 bits wide and 256 words deep, and I want to change it to24 bits wide and 256 words deep. However, I don't want to changes any of the other parameters associated with the 48x256 fifo, and I want to create a new IP and not over write the 48x256 fifo. Or if I have a PLL and want to change some of the frequencies and save it off as a new PLL IP without destroying the original PLL IP.
I know that I can always create a new IP, but sometimes all you want to do is change one parameter without changing any of the other parameters and then save the changed IP off as a new IP. In these cases, it would be easier to edit an existing IP than to start over and create a new IP.
Thanks for your assistance,

Super ContributorSo if you're using Pro edition, like I said you can just open the .ip file for the existing IP variant and save it as a preset. Then, when you reopen the IP Parameter Editor for the same IP to create a new one, give it a new variant name, select the preset, and adjust what you need.
I believe in Lite/Standard, this same process would work for some IP that support presets. I don't have Standard handy to check right now.

Unfortunately, I am using Quartus Lite 20.1.1 and not Quartus Pro.
How do I know which IP supports presets in Quartus Lite?
Can you give me an example of "some IP that supports presets" so that I can try it out?
I don't believe that I have ever seen the "preset" capability in the Quartus Lite IP Catalog.

Any newer version IP that opens the full "IP Parameter Editor" (splash screen appears when you add the IP; based on Platform Designer) as opposed to the older wizard would support this.

I tried the Platform Designer as you suggested. However, the only FIFO that if provided for the Cyclone 10LP was one with an Avalon Interface which I don't want. Besides that it was not evident how to save off parameters. Is there a tutorial in the Quartus User's Manual that explains the process?
Thanks for your continuing support,
