Cyclone 10LP license requirement for floating point arithmetic - Cyclone 10LP license requirement for floating point arithmetic I encountered the following error message when compiling floating point subtraction IP of Cyclone 10 LP in Quartus Prime Version 23.1 standard edition. Error (12006): Node instance "altfp_add_sub_component" instantiates undefined entity "altfp_add_sub". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP. A similar message posted in " https://community.intel.com/t5/Intel-Quartus-Prime-Software/Why-won-t-the-altera-floating-point-add-sub-ip-synthesize/m-p/653389?profile.language=pt&countrylabel=Latin%25252525252525252520America" solved the problem by using Quartus standard and pro editions. As I am already using Quartus Prime Version 23.1 standard edition I am not sure what caused the error message. Has anyone encountered this error message while running floating point subtraction IP of Cyclone 10 LP? Do I need to get a paid license to use it? Replies: Re: Cyclone 10LP license requirement for floating point arithmetic Hello, Please use FP_FUNCTIONS IP for latest Quartus. regards, Farabi Replies: Re: Cyclone 10LP license requirement for floating point arithmetic Hi, I don't think that the solution is correct. The problem has nothing to do with Lite versus Std. Quartus version. rather looks like altfp_xxx functions are deprecated. Use FP_FUNCTIONS Intel FPGA IP instead. Regards Frank
