Cyclone IV FPGA Speed Grades - Cyclone IV FPGA Speed Grades We are using this device (EP4CE40F23C8N) for our video mixer. We can't find the same device but were offered a similar with different speed grade (faster speeds C6N, C7N suffixes). Would that hardware change be compatible using the same program from C8N or it requires a change in the program setup?

Regards, Nazrul Naim Replies: Re: Cyclone IV FPGA Speed Grades Great new! Thank you for the prompt replies Replies: Re: Cyclone IV FPGA Speed Grades C6 and C7 are just faster speed grades of the C8 device. Program image is identical. Should work just fine unless you did something really weird in the original design. Replies: Re: Cyclone IV FPGA Speed Grades Hello RobertoG1, Thank you for posting on the Intel® communities. We would like to inform you that we have a forum for these specific issues and products, so we are moving it to the "FPGA, SoC, And CPLD Boards And Kits" forum so you can get better support for this matter. https://community.intel.com/t5/FPGA-SoC-And-CPLD-Boards-And/bd-p/fpga-soc-cpld-boards-kits Regards, Deivid A.
