File Hierarchy

The top-level directory into which the ZIP file is unzipped contains several subdirectories.
The HyperLynx project files are all located in the hl_projects subdirectory. Any
example project can be opened by double-clicking on the respective FFS file in Windows
Explorer or by starting HyperLynx, going to File/Open Schematic..., and then clicking on
Open Linesim File.
Model files are located in the subcircuits under the top-level project directory.
Subcircuits are referenced by the HyperLynx schematic symbols. The INC files containing
the simulation parameters are located under the testbenches directory along with the
configurator executable programs. There should be no reason to manually modify these
files. All modifications are made via the HyperLynx Graphical User Interface.

To prevent errors or warnings when the project files are moved to a different directory
(or computer), replace the path listed on the last line in the PJH files (located in the
HL_projects subdirectory) with a relative path:
INIFILE=.\S6_kit.ini.
Note:
HyperLynx automatically replaces this relative path with a full path when opening the
project. Therefore, this change should be made every time the project is moved or copied to a
different location.
For better convergence, set ForceFixedStep = 0 under the [SPICE] keyword in the
bsw.ini file in the HyperLynx Installation directory.
