Unable to run lpm_inv

Hello , 

I have the MAXII Micro kit with the EPM2210F324C3. 

 

I have a small schematic project with a simple lpm_inv block. It compiles fine and downloads fine. But I'm unable to see any change on the output of the inverter when I change the input. 

 

I'm extremely new to this and any help would be appreciated. My project is attached.

Your test waveform doesn't drive the inverter input. You actually don't change the input.

Thanks for replying, but how do you drive it. Is there an extra component that has to come beween the pin and lpm_inv? 

 

For testing, I directly apply a signal to Pin C11.

I was referring to your simulation, that didn't drive the inverter. It works if setup correctly. If you have a problem with the real hardware, there's most likely a different problem, e.g. missing supply voltages. You can see from the compilation results, that the inverter should work.

Hi FvM, 

I created a vwf to simulate it, but the output does not wiggle with input(attached). 

The simulation is in functional mode and I generate the netlist before clicking start. 

 

Thanks.

Could anyone have a look at my project and simulation. 

The simulation checks out, but I am unable to get it working on the dev. kit. 

 

Thanks.
