VHDL variables in Quartus v9 simulation

Hi, 

 

I'm trying to simulate a design in the Quartus v9 simulator. In the VHDL design there are variables within a process that I'd like to view in the simulation, but in the node finder they don't show up. I've tried various filters ( Pins:all, Register:post-fitting, etc), but the signals are not to be seen. Does the simulator support showing variables?

No all variables are visible in Quartus sim. Try either ModelSim or change variables to signals.

the quartus simulator only runs a post place and route simulation. Depending on how you used your variables, they may have been converted to intermediate logic. 

 

I suggest using modelsim.

The QuartusII 9.1 internal simulator also supports 'functional' simulation, which is RTL and run after Analysis and Synthesis..  

But the suggestion to use ModelSim definitely holds, writing testbenches is a lot more powerful than drawing waveforms.
