SPICE netlist error in schematic

[Halifax]

I get the following error messages when I run the simulation.

Error: SPICE Netlist Error in schematic RefDes '', element '_uc2fffffffe*************':  Unsupported component prefix type '_' 
Error: SPICE Netlist Error in schematic RefDes '', element '<unknown>':  Due to errors, the component '_uc2fffffffe*************' has been omitted from the simulation 
Error: SPICE Netlist Error in schematic RefDes 'u1', element 'e_u3_e7':  Unknown controlled source table syntax in 'e_u3_e7:ad8336__vga__1'  
Error: SPICE Netlist Error in schematic RefDes 'u1', element 'ad8336__vga__1':  Due to errors, the component 'e_u3_e7' has been omitted from the simulation  

This just a test ckt for AD8336 chip.

thank you

Hi Halifax,

              I took a look at your circuit. It seems that the AD8336 component has not been created properly. There seems to be no spice model linked to it and thus you are seeing simulation errors. You can go through the component creation tutorial in the link provided and try to create the component again.

Hope this helps.

Hi,

Can you post your circuit so we can take a look at it.

Morning Tayyab R

im unable to attach i get the following error:

Please correct the highlighted errors and try again.

Hi,

You can place it in a zip folder and upload it.

[olorato]

thanx.. here you go.

Hi,

The reason you have all these errors is because you have not created the layout components correctly. The header and connector should be layout components but they seem to have models which is not correct. When you are going through the component creation, you should select Layout Only components.

I have written a small document which shows you what you will need to do for all such component on your design.

Hope this helps.
