Agilex 5 - LUTs

Hi,

Can you attached 2 design for me to investigate?

1) the older device that demonstrate it work.

2) the agilex 5 design.

Thanks,

Best regards,

Kenny Tan

Hi Kenny,

I added the designs to the supportrequest that was opened.

I added some information to your email as well, can you take a look and get back to us?

Just to let you know after the discussion, the old method of find the equation using ECO can still be done on the latest version of Quartus.

In Quartus Pro ECO is supported primarily only as a Tcl interface. There is some documentation on this here:

https://www.intel.com/content/www/us/en/docs/programmable/683873/current/an-922-using-the-eco-compilation-flow.html (AN 922, see also section 1.3.1) and here:

https://www.intel.com/content/www/us/en/docs/programmable/683641/24-3/using-the-eco-compilation-flow.html (Documentation in Quartus User Guide) and here:

https://www.intel.com/content/www/us/en/docs/programmable/683432/24-3/tcl_pkg_eco_ver_1-0_cmd_modify_lutmask.html (Tcl API documentation)

An easier way to get comfortable with this mechanism is to use the Fitter Toolkit, which is an executable shipped with recent versions of Quartus but only accessible via command-line.

The command to run Fitter Toolkit is quartus_ftk.

You can check your email for more detail information. Thanks

Have you try to compile using RTL design instead of WYSIWYG for your project? Then use the ECO method.

Since tennm_lcell_comb might not work exactly as in old legacy devices.
