Global clock control assignment for Arria10

[AEsqu]

Hello,

I want to set the global clock control location for the arria 10 FPGA,

In the past I used the GLOBAL_SIGNAL_CLKCTRL_LOCATION

https://www.intel.com/content/www/us/en/docs/programmable/683084/current/global-signal-clkctrl-location.html

But it is not supported for the Arria 10.

I tried to used the location assignment instead,

set_location_assignment CLKCTRL_2A_G_I28 -to rfd_ic_i|u_top|u_core|u_rfd_clockshop|i_mcu_cgu|i_final_stag0_clockgate|i01_cnhlspd|Q_cZ

it shows a green check mark in the edits assigns windows

but it is not taken into account (see picture).

What can I use to force the global signal location for the Arria 10?

Thanks.

Alex.

Hi,
I never came across this logic option. Can you explain why you need it for your design?

[AEsqu]

To force Quartus to use a global clk control close to the area where it is critical.

I used it in many FPGA's and projects to get better or consistent timings over runs.

So just using the "Global Signal" assignment is insufficient?  Is the Fitter choosing strange locations for the clock control block?

Hi,

You can use the "GLOBAL_SIGNAL" setting: https://www.intel.com/content/www/us/en/docs/programmable/683296/22-1/fitterassignmentsglobalsignal.html

I already use the global_signal to use the global clock routing.

This is on top of that, for the clk control selection that connects the node to the global switch.

Hi,

Make sure you're assigning it to the correct clock buffer node name. For example, this clock buffer node ends with "~CLKENA0"

I've tried it from my end and it is working.

Thank You Nurina,

That works great!

Note: I couldn't respond before because I changed my smartphone and the old one was at home, which is the only one that receives the authentication code.

How to move the Microsoft authentication to my new smartphone?

Kind Regards,

Alex.

Hi Alex,

Glad to hear that works for you.

Here's what you can do to move your Microsoft Authenticator to a new phone: https://support.microsoft.com/en-us/account-billing/change-your-two-step-verification-method-and-settings-c801d5ad-e0fc-4711-94d5-33ad5d4630f7

I think you're better off asking in the Microsoft forum though.

Hi,

I couldn't transfer the Intel login account, I created a new one based on another email.

Have a nice day.

Alex.
