2. What is the J0 symbol on the schematic screen (Figure A-2)?
The J0 symbol appears unconnected on the schematics screen and must not be
removed from the schematics. The J0 symbol inserts global simulation parameters,
such as .TEMP and .option compat (the HSPICE compatibility switch for Eldo) into
the project. These parameters are managed automatically by the configurator
programs. Removing J0 results in incorrect simulations.
