Disable pin count error for simulation in QuartusII 8.0

How can I make Quartus shut up and compile when I'm trying to compile a part of my design for simulation purposes, it gives me an error about the design having too many pins for the device I have selected. I just want to simulate this part, those pins are intended for internal connections. This is QuartusII 8.0 and I'm using block diagram entry.

Use virtual pins for all top-level ports of this portion of the design that are not device pins in the full design and that are not a clock. The assignment for this is in the Assignment Editor. Virtual pins are documented in the Quartus handbook. 

 

Virtual pins are meant for compiling one portion of the design for bottom-up incremental compilation. I don't know whether you'll run into any simulation issues with them.

Can't you comment out those signals in the entity or even those parts of your design?

Another option would be to use modelsim to simulate, then you can access any signal.

The original poster is "using block diagram entry", which can't be simulated directly with ModelSim. The .bdf file(s) would need to be converted to VHDL or Verilog using "File --> Create / Update --> Create HDL Design File for Current File". 

 

I forgot that there are more virtual-pin restrictions than just the clock input. The Quartus handbook lists which ports can't use the virtual-pin assignment.

Missed that.  

 

Sorry!
