Hi, I have been running XL from an spice impoeted netlist and it has been working great on lower level blocks. When I move up the next level in hierarchy XL doesn't add the connectivity for the lower level blocks I created, it is giving an error complaining that the block doesn't match and is looking for the lower level devices in the block. I found that if I remove all lower device statements in the SUBCKT (make it an empty SUBCKT) all works fine. This is ok but if the block needs to be editted it can't be done in XL since the SUBCKT in the netlist is empty. Is there a way to stop this behavior? Thanks in Advance, Tim
