Synthesization of design in Quartus II using Precision RTL Synthesis

--- Quote Start ---

Hello,

I'm synthesizing my to-level-design also known as zpu_core.bdf. The strange thing is, the error appeared like this:

Error: Precision Error:# Error: Design zpu_core not found in HDL files.

I really don't have any idea why it was trying to find my design in HDL files.

Solution?

Export .bdf file as HDL file and use this HDL file in Precision RTL.

Hello,

To Miserten, i have to use precision because the bdf file contains two block which each of them has vhdl codes.The vhdl files have problem when i synthesize with Quartus Synthesis.

To vizzie, how to export this .bdf file as HDL file?? This bdf file has two block which have vhdl codes.

Hope to see from you soon.

Regards,

Bruno Kasimin

File -> Export is the obvious option. But in case you are unable to export the entire schematic (which I don't see why it cannot happen), export each of the blocks and then simply write the top-level entity in HDL joining these two blocks the way they are connected in the schematic. This doesn't need any great HDL coding, you will only have to join the ports correctly. Export has some issues, so make sure you 'Update' your designs if you make any changes in bdf.
