Simple RAM bfm generation in QSys gives generation error

[Altera_Forum]

Hello, 

 I am getting started with the whole QSys tool and I am learning by following tutorials and videos. In particular, I want to be able to perform simulations of what I am constructing in ModelSIM. I started off watching this video: http://www.altera.com/education/demonstrations/qsys/simulation/simulation-online-demo.html .  I did exactly what is done in the video. I added an On-Chip RAM and exported the clk, the s1 and the reset signals.  https://www.alteraforum.com/forum/attachment.php?attachmentid=7830  https://www.alteraforum.com/forum/attachment.php?attachmentid=7831   However, when I want to generate the testbench and BFMs it gives me an error I don't really understand. It tells me that there are two reset ports. However, I only see one. What is going on?  https://www.alteraforum.com/forum/attachment.php?attachmentid=7832 https://www.alteraforum.com/forum/attachment.php?attachmentid=7833   Error: TB_Gen: More than one reset ports found Error: get_instance_interface_port_property ram_inst ram_reset1 ROLE: null Error: Error: TB_Gen: More than one reset ports found get_instance_interface_port_property ram_inst ram_reset1 ROLE: null Error: There were errors creating the testbench system.   What is the cause of the error and how do I fix this? Thanks.

Hi Alex, which Quartus 2 version are you using? 

I've always used this tutorial with version 13.0 and 13.0 sp1 without any problem, everything worked correctly. Now I have installed version 13.1 and it does not work anymore. It seems that it's another Altera bug. Furthermore I kept the older version (13.0 installed) in the same PC, and now it doesn't work it either....this seems more strange  Luca

I found that the problem is due to the new On-Chip RAM, that has 2 reset inputs: if you want to manage thus problem you have to put a clock source and connect reset_out and clk_out of the clock source to the RAM and then export the clock_source clock and reset inputs

Great, I'll try that once I get back to work.
