out_of_context mode equivalent in quartus tool

Hi Forum, 

I am a beginner in using quartus tool. I have a question regarding I/O buffer insertion in quartus. Earlier I used Vivado tool for synthesizing my design and I used out of context mode in vivado (which will make sure that no IOBUFs are getting inferred for submodules) when I did analysis on sub modules in my design. I wanted to know the out_of_context equivalent in quartus tool or how to tell quartus tool not to infer IO buffers. 

 

Thank you, 

Vamsi

There is no OOC mode in quartus. 

But what you can do is declare signals as "virtual pins". Using this, you can synthesis a module without it attempting to connect your module ports to IOs
