NCO Simulation help

[Altera_Forum]

Hello, 

 I am new to FPGA/VHDL and I am trying to generate a sine wave using the Altera NCO IP Core. I have instantiated the IP component and I am using the test bench generated. When I try and simulate the design using modelsim I get numerous errors similar to the one below:  Error(suppressible): (Vsim-10000) nofile(39): unresolved defparam reference to 'acc' in acc.lpm direction. Time : 0 ps iteration: 0 instance: /sine_ip_core/uo/nco_ii_0/ux000 File: nofile.   Does anyone have any suggestions to solving this issue?  Any help would be appreciated.  Kind regards

Hi, 

 1.Are using tcl scripts for setting up model-sim?  I have tried to simulate it is working. with the help of tcl script generated and few comments. Can you share the screen short of the error. Attached model-sim transcript log file for reference.  Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)

Thanks for your response. 

 I am simulating by setting the test bench file in Alteras simulation settings and then clicking Tools -> Run Simulation Tool -> RTL simulation. This prompts modelsim and then I get the following errors:  https://www.alteraforum.com/forum/attachment.php?attachmentid=14621    I have not encountered using TCL scripts to simulate as of yet...  Kind regards

The NCO core files are encrypted and can't be used by Modelsim. You need to generate a dedicated simulation model and - as I guess - import it manually in your simulation project.
