DxDesigner / Hyperlynx Analog Top level

Hello all,


I am new here and this is my first post.

I recently downloaded the DxDesigner/PADS evaluation SW since the company I work for will soon purchase the PADS suite.


I tried the analog simulation on a schematic sheet and I was very pleased with its capabilities.

However, when I put my schematic in a block to make a top level sheet and run it from there I get the message:


"error - ground is an illegal node in schematic"


This happens whether the block is created top-down or bottom-up.


Fearing that there is something wrong with my schematic, I tried a very simple circuit, just one resistor, VCC and GND.

The top level block has only the VCC and GND connections with the tool's special symbols.


Any idea of what I do wrong?


Thank you in advance
