Evaluation Package of PADS

   PADS evaluation package is unique, because it is the first EDA program
  to be provided as Shareware. This means that the Evaluation Package is
  not simply a demo disk, but a complete, working copy of PADS. It contains
  all of the capabilities of the commercial program, and can produce a
  complete set of netlists and drawing etc. It is only limited in the size
  of the circuit you can create.
   PADS includes PADS-Logic and PADS-PCB. PADS represents a new concept in
  low-cost schematic and PCB capture software. Its intelligent, multi-sheet
  database introduces a new level of functionality in PC-based schematic 
  and PCB package.
  You may use the PADS-Logic alone, or in conjunction with the PADS-PCB
  Evaluation package. 

  "PADS-Logic"
   - Schematic design max 2 pages       - Output Various Netlist
   - Include over 6000 parts and create new part
   - MS-DOS based software              - Be able to print and save
  
  "PADS-PCB"
   - Pattern design automatically from Netlist
   - Automatic routing and layouting    - Be able to print and save

School version of HiWIRE II

   The HiWIRE is developed in Wintek Inc. in USA. The school version
   is limited in size of circuit, and not create new library.
   But in another way , library is able to create. So this school
   version is very convenient for the personal electronic handicraft.
   This HiWIRE is included both Schematic editor and Pattern editor in
   the same program. You can print out schematic or pattern, and can
   save in disk.

Evaluation version of PSpice/Win

  PSpice is developed in MicroSim Corp.
  The Design Center - System 3 Evaluation version includes Schematics,
  PSpice, Probe, the Stimulus Editor, and Parts programs.  
  With the Design Center - System 3 Evaluation version, the Schematic
  Editor is limited to one page schematics, A-size pages only, and a 
  maximum placement of 20 parts on the page.  The maximum circuit size
  is 64 nodes and 10 active components (or approximately 2 opamps).
  Only a subset of our Model and Symbol Library is included, and the
  device characterization utility is limited to modeling diodes.
