Quartus_syn and nested pragma not supported

I have a bunch of vhdl code which needs to be seen from Altera tools but not others, so I am using "altera translate_on/off" nested inside "pragma translate_off/on" directives: library ieee; use iee...

Hi,


Pragma is not supported in pro version check this link https://www.intel.com/content/www/us/en/docs/programmable/683475/19-4/remove-non-standard-pragmas.html

Intel® Quartus® Prime Pro Edition synthesis does not support the vhdl(verilog)_input_version pragma or the library pragma. Synthesis in other Quartus software products supports these pragmas. Remove any use of the pragmas from RTL for Intel® Quartus® Prime Pro Edition migration.

Remove the pragma and just use it with other synthesis tools. Pro version is more strict.


Thanks,

Regards,

Sheng

Hi Sheng,

Thanks you for the tip, even though it seems to contradict the documention: Intel® Quartus® Prime Pro Edition Help version 23.1 - vhdl_input_version Synthesis Directive & Intel® Quartus® Prime Pro Edition Help version 23.1 - library VHDL Synthesis Directive

Anyway in my case this is related to the "synthesis_off/on" directives. They are understood by the tool (and you can disable its support if needed), but contrary to others vendors tools and now old quartus_map, the quartus_syn doesn't support nesting it, as in my example.

Best regards,
