in 20.1 synthesis embedded pragma support for vhdl --synthesis library xxx appears to have been removed or is it part of the licensed versions now ?

free edition targeting cyclone 10 GX in 20.1 the embedded pragma --synthesis library xxx is not working.

Hi Chris,

What do you mean by not working? Is there any possible error message(s) and snapshots you could provide?

Refer to link below for VHDL Synthesis Attributes and Directives

Thanks,

This pragma works in previous version of quartus.
