CycloneV PLL and PLL reconfig simulation

[AGofs]

I've generated PLL and PLL_reconfig function with Quartus18.1.

The PLL receives 20 MHz and sends out 25 MHz. I want to change the frequency of the outcoming signal from 25 MHz to 50 MHz.

I'm new with CycloneV and with Quartus18.1

I cannot implement simulation not in Model-Sim nor in Native Link.

N.B. I've read AN-661. Is it necessary to use AVALON-MM?

Good evening,

I still have a problem with simulation.

When I'm trying to simulate Altera PLL and Altera PLL Reconfig Mega-Function via Native Link I'm getting the following error:

[AGofs]

# ** Error: (vcom-7) Failed to open design unit file "C:/Alex/my_designs/18_1/PLL_reconfig/PLL_reconfig_001/cycloneV/PLL_RECONFIG_20_25.vho" in read mode.

# No such file or directory. (errno = ENOENT)

[AGofs]

Indeed, there is no such a file. But I have get PLL_20_25.vho for Altera PLL Mega-Function, and PLL_RECONFIG_20_25.hdl for  Altera PLL Reconfig Mega-Function. Why file . vho doesn't generate for  Altera PLL Reconfig Mega-Function?How can I control it? When I'm trying to simulate the design via Model-Sim10.5B, then no waveform generated by Altera PLL before reconfig and after reconfig.

Hi @AGofs​ 

I would suggest that you view the following how-to videos to simulate your design via Nativelink.

Hi JwChin,

thank you for your replay.

I've simulated my projects (include PLL dynamic phase shift) via Native-Links many times .

The question is another: in order to simulate via Native-Link , Quartus shall produce xxx .vho file for Altera PLL Reconfig Mega-Function.

But it doesn't.

The file xxx.vho Altera PLL Mega-Function has been generated Instead.

why? Is it wrong? How can simulate frequency reconfiguration on CycloneV?

[AGofs]

Hi JwChin,

I found the way to execute simulation directly via ModelSim-10.1.

I think, you can close the case. :-)

@AGofs​ I am delighted to hear that. Closing the ticket.
