Basic Functions / Arithmetic is missing in Platform Designer IP Catalog - Basic Functions / Arithmetic is missing in Platform Designer IP Catalog I was planning to use Platform Designer to simplify the integration and pipelining of multiple FP_FUNCTIONS blocks. However, this IP, or even the whole Arithmetic library seems to missing under Basic Functions. Right now, I'm using v20.1 for Quartus Prime Lite. Is this a problem with this version of Quartus? Or is it just that Arithmetic is no longer supported in Platform Designer? Replies: Re: Basic Functions / Arithmetic is missing in Platform Designer IP Catalog Hi, Previous version platform designer arithmetic section only has ALTERA_FP_MATRIX_MULT IP core. Starting from version 20.1std onwards, ALTERA_FP_MATRIX_MULT IP core had been discontinued check this link https://www.intel.com/content/www/us/en/docs/programmable/683750/20-1/about-floating-point-ip-cores.html . Therefore, arithmetic section had been removed. Thanks, Regards, Sheng Replies: Re: Basic Functions / Arithmetic is missing in Platform Designer IP Catalog That's odd. I have the Arithmetic group in PD but I'm using the latest Pro with a license, so I'm not sure if this is a Lite vs. Pro difference or you somehow have a bad installation. You may want to try updating to the latest lite edition which I think is 23.1. You could either build a custom component in PD, adding an Avalon wrapper around the IP created in Quartus itself, or export whatever interfaces you need to connect out of your PD system and instantiate and connect in HDL.
