Differences in VHDL 2008 support between Standard and Pro version

Hello, Cleaning out some code to get a more reusable and family independent code base, I noticed a difference in VHDL2008 support between the standard (20.1) and Pro(20.4) versions of Quartus I am...

Hi LukasR,


This is because the Quartus Pro version and Standard version are using different synthesis engine under the hood.

In your code compilation using the pro version, does the RTL viewer show the expected behavior result? If yes, then you may check your email.


Thanks.

Hi Ven Ting,

Thank you for your reply.

Running the code in the src folder below (demo toplevel) in a Quartus Prime Pro 2020.1 does give the expected RTL-viewer output:

This uses the Cyclone 10 GX as device family, as the Cyclone 10 LP is not supported.

The difference in which engine is used is what I feared for.

Is there any hope for a workaround so this code could also be used to work on FPGAs like the Cyclone 10 LP or other/older Standard version supported FPGAs?

Kind regards,

Lukas
