Question about Intel Agilex FPGA Development Board: Which Quartus Version to Use and Pricing Informa

With Agilex, just use the latest version. Right now it would be Pro version 23.3. There are 4 releases per year (<year>.1 - .4).

The price used to be on the comparison list (https://www.intel.com/content/dam/www/central-libraries/us/en/documents/2023-11/quartus-prime-comparison-infographic.pdf) but it's not there anymore. I think it's $4K for an annual subscription.
