ContributorEdit IP Catalog IP and saving to different name
Super ContributorWhat exactly do you want to change? Some IP let you create presets that you can select the next time you add the IP to a design.
WShep1For 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,

So 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.
Thanks for your assistance,
