Error compiling Altera Uart 16550 IP Core Cyclone V

Hello, 

 

+ Quartus 17 Prime Lite edition 

+ Windows 7 64 bits 

+ Altera 16550 Compatible UART 

 

I'm trying to use this module via avalon/axi bus. I added the module via qsys with no problems and I compiled a C software using the HWLIB and SoCAL libraries delivered by Altera.  

When I try to compile the project I get this error: 

Error (210039): File xxxxxx/de10nano_uart_16550/quartus/output_files/led_test_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.  

 

I understand what the error means but I think there is a mistake here given that I'm using the IP Cores delivered with Quartus and no other sources, besides there is no info on the documentation[1] about this megafunction being limited or how can we buy it. 

 

It generates a limited sof file which works OK while being connected but some implementations are not working (like FIFO) 

This is the first time I get a problem using Qsys + IP cores so I guess it is a bug on Quartus ?

Hi, 

 

We used this IP core on Quartus 15 and it certainly required purchase of an Opencores License through Altera then, so I guess you will need that if you want to do more than just evaluate it. 

 

Hope this helps,

Could you give me please a reference price about what you paid? 

 

It feels strange that FIFO isn't working. I will try with the 30 day trial for complete Quartus, maybe that way I can unlock it to test FIFO. 

 

PS: Sorry for the double post, maybe an admin could join them ?

Hi, 

 

I can't recall a figure. I believe Altera probably waved the license cost because we are a big customer. They still needed to provide us with the key for Quartus though. I don't think the cost was ever very high but Altera don't own that IP. 

 

I can't remember any functionality issues without a license, only the inability to generate anything other than time limited SOF files.

It seems like FIFO is working OK but not reporting correctly de FIFO size. 

I'll debug it a little more using the time-limited SOF. 

 

Thanks for the help!
