Honored ContributorSorry disturb engineers, I am a student in graduate design using the FFT and the RS of the IP core, and now I want the hardware to test my program, so ask for a free trial ALTERA IP core is only can be downloaded to the hardware again? How valid is going on?
thanks for your time!
Honored ContributorI don't understand your question... If you have a development kit, you have a CD with the Quartus software on it. You can also download Quartus from the Altera web site.
You can install the web edition which is free and will let you try your design on the development kit.Honored Contributorthank you for you timely reply.I am very sorry not have express my problem clearly.I just want to know how much time can the free IP be downloaded to the device?I heard someone that it can only be downloaded to the device just for once,is it that true?
i want to test my program on the hardware with the free IP core. thank you for your time !can you reply me soon? best wishes!Honored ContributorYou can download it multiple times. It will only work if you keep the USB cable connected and don't close the opencores evaluation window.
If you disconnect the SB cable it will work for a limited period (1 hour, usually).Honored Contributorthank you very much! After I verify my program I may let the cable disconnected.but the next time can I use it also?
Honored ContributorI mean can i use it the second time after a few days I disconnected the cable ?
Honored ContributorI mean can i use it the second time after a few days I disconnected the cable ?
Honored Contributoranyway thank you very much!
Honored ContributorYou can reuse it after having disconnected the cable, but you will need to upload your design into the FPGA again first.
Honored Contributorthank you again for you timely reply !I can reuse it after having disconnected the cable, but I will need to upload my design into the FPGA again first.so I need to download my program to the device(EP1C12Q240C8),but I don't need to download the IPcore from the ALTERA website again?is that right?can i use it without connect the internet?
thank you !Honored Contributorwhen I want the hardware to test my program, I encountered some problems when downloading:
the problem :file c:/documents and settings/ofdm/ofdm_sch_time_limited.sof contains one or more time_limited megafunctions that support the opencore plus feature that will not work after the hardware evaluation time expires.refer to the messages window for evaluation time details. how can i solve this problem? thanks for your time!!!
